This vintage Corneta machete from the '50's or '60's of the previous century was made by Weyersberg in Solingen, Germany.
Later the brand was sold to South-America, i think to Imacasa.





The machete was completely unsharpened when i bought it, but when i saw it's tapered blade and felt the balance i just knew it had to have a good edge.
Reprofiling was done on the Tormek and refining to a slightly convex and razorsharp +/- 30 degrees inclusive edge on the grit 60 & 180 Rubber Wheels.
The chromed blade is quite flexible and the steel is both harder as well as more wear resistant than previous machetes i've sharpened.

Specs:

Overall length: 21.3 inch (54,0 cm)
Blade length: 16.0 inch (40,7 cm)
Blade thickness: tapering from 2,25 mm before the handle to 1,25 mm just before the point.
Steel: chromed carbon steel
Handle material: Natural horn with brass rivets
Weight: 307 grams
 
2013 Spyderco Forum Knife Native5 C41GPGR5









The Spyderco 2013 Forum Knife is a reflection of both the deep tradition and commitment to innovation that characterize Spyderco.
It is based on the Native5, the latest evolution of one of our most popular US-made designs.
The full-flat-ground blade is machined from premium CPM S110V steel—an ultra-high-performance, state-of-the-art alloy that includes cobalt, niobium, molybdenum, vanadium, and almost three percent carbon.
Its handle is also highly evolved, featuring full skeletonized stainless steel liners, a stainless back spacer, and a meticulously crafted backlock mechanism that took literally years of R&D to perfect.
The handle is encased in green G-10 scales with a distinctive diamond-cut texture pattern and the liners, scales, and lockbar are all expertly hand sanded for an exceptional fit and finish.
The 2013 Forum Knife will be the first production knife to use this new handle material with its very unique texture.
A polished four-position hourglass clip completes the package, supporting tip-up and tip-down carry on both sides of the body and making the knife’s operation completely ambidextrous.
A shining example of the US factory’s craftsmanship, this unique limited-edition knife is laser engraved on the reverse side of the blade with “Spyderco Forum Knife 2013.”

Nick Powell is an Australian friend of mine, and although he is a skilled carpenter in daily life, a couple of years ago he discovered that his true passion is making knives.

Besides making useful models for friends & colleagues in the Brisbane area where he lives & works, once in a while he tries his hand at making Scagel reproductions, purely based on pictures.
For the handles he uses the same kind of materials that Scagel himself could have used also, but for the blades he chooses various modern stainless steels like for instance CPM-S35VN.
The heat treatment is done by one of Australia's leading heat treaters, and although Nick only made a few of these models yet they are already starting to gain a following among his growing customer base.
Currently he still does one knife at a time, but as soon as he can afford a professional grinder he's probably going to make them in small series.

A few days ago the postman brought me a surprise present: a small but sturdy wooden crate containing Nick's interpretation of this original Scagel, based on the single photograph below:



And this is Nick's version:











This is what Nick himself has to say about his work:

" This knife was actually started for you shortly after doing my first Scagel, but I had given up on it many times after troubles grinding those bevels.
It is as close to the original model as I could make it, and I even counted the washers and matched them to the same amount as the original.
I used my favorite steel because I wanted you to test it out, and it's a good balance of sharpening ease in the field and edge retention: hardened to 60-61 Rockwell (so maybe 62-64 in the edge), while the finish is 600 wet and dry (but I need practice as you will see)
The pommel is navy bronze for corrosion resistance, the guard is brass, and the washers are industrial compressed paper similar to spacer material.
The leather is compressed embossing leather in black and soaked in antique dye by me.
Brass spacers , stainless steel and copper as you know, and the handle is shaped for you by eye.
The leather sheath is clear embossing leather stained with acrylic antique leather stain and finished with saddle makers sealant.
The guard locks into the sheath for close carry and so the knife won't come out if you forget to close the button stud.
My design as far as I know, but I'm sure it's been done Lol."

Overall length: 30,7 cm
Blade length: 17,5 cm
Blade thickness: 4,75 mm (ricasso)

Extremely rare Puma 929 Goldfish (also known as Rainbow), a micro-multitool meant for flyfishing.
Bought it from the unsold stock of a long gone knife & fishing store, and the tool dates back to the '60's of the previous century.
It's in unused condition.



In the green box was also the little catalogue explaining it's use.

 
Some time ago i scored this vintage 4-liner Puma 959 hunting folder made in 1986.
Still brand spanking new in original yellow/green box and complete with soft leather pouch & papers.
Never carried, used, or sharpened and always kept inside the box.
Inlayed in the front sambar stag panel is a real silver shield where the buyer could have his initials engraved.

















 
Vintage Al Mar Denali mid-backlock folding knife with hollow ground blade from the 1980's and made in Japan. (probably by Moki)
The cocobolo handle is inlayed with a gold shield picturing a fighter plane and the text "United States Navy Fighter Weapons School".
The 1986 movie "Top Gun" with Tom Cruise and Kelly McGillis was partly filmed on the grounds of this elite school for US Navy pilots.
Bernard Levine thinks this version with the gold shield was a special edition, not standard production.
The original edge measured about 35 degrees inclusive and wasn't really sharp, so i changed the angle to 30 degrees inclusive with a treetopping sharp bling & bite finish.

Vintage Puma 3589 Jagdnicker from 1977.
The model was designed by German Oberforstmeister (Chief Forester) Walter Frevert in the '50's of the previous century, en to this day it's highly regarded by hunters because of it's efficient design handcrafted from high quality materials.

"Abnicken" is the German word for a certain method of providing the coup de grace, in this case to wounded deer.
To perform this act the hunter bends down the head of the deer with one hand, and then stabs the knife precisely between the skull and the first vertebra with his other hand.
This severs the spinal cord which ends the life of the deer quickly and as painless as possible. (also see the last picture which describes this method in German).
For this specific purpose the Jagdnicker has a very sharp & swedged point which at the same time is relatively wide, and also placed outside of the centerline of the blade.
Due to this design the point has a strong tendency to glance off of bones and into the soft tissues, much better than a symmetric hunting dagger blade.
The 3589 Jagdnicker is further used as a strong allround hunting knife that seems to appeal to both hunters & collectors alike.



















Specs:

Overall length: 9.2 inches (23.4 cm)
Blade length: 4.72 inches (12.0 cm)
Max blade thickness: 5,3 mm

An original MOD Tempest:



Michael Janich on his design:

The final form of the Tempest is a bit different than my original design, but I'm still very proud of it and pleased to carry mine on a daily basis.
Here are the major design features and their reasons for being:

1) A Bowie-style blade provides plenty of "belly" or curve to the cutting edge for efficient slashing, yet keeps the point of the blade on the knife's centerline.
This ensures a direct transfer of energy during a thrust and keeps the knife from drifting during penetration.
The wide blade profile produces a wide wound channel during a thrust and allows for a gradual taper of the blade bevel.
This makes the blade strong, but still allows it to be sharpened to a keen edge.

2) A 3.5-inch blade is legal to carry in most areas (in fact, it is the maximum legal limit in Colorado - a personal consideration) yet is long enough to reach vital anatomical targets such as the carotid, the brain (through the eye), the liver and spleen, and (on thinner opponents) the aorta.

3) The tapered handle shape of the Tempest allows the user to focus the strength of his grip on the last three fingers (middle, ring, and pinky) to anchor the handle to the fleshy pad of the palm.
This increases the surface area in contact with the handle and allows for efficient management of "impact shock" when the knife hits a hard target.
The tapered shape also provides a striking surface on the butt of the handle (though it is smaller than I wanted it to be) that can be used for striking with the knife open or closed.
Finally, the index finger cutout is a functional guard that, along with the tapered handle, keeps the hand from sliding forward during the impact of a thrust.

4) The pronounced ramp on the back of the handle and extending over onto the back of the blade is designed to allow the thumb to extend forward.
This further tightens the grip of the hand and provides a positive index for the thumb to guide the blade.
I'm a big believer in using the thumb as a guide to allow the blade to be employed instinctively.
This is similar to the Filipino extended thumb grip, but does not require that the thumb be held away from the back of the blade.

5) The reversible clothing clip allows the knife to be carried point up in the pocket (mine is the only MOD knife with this option).
This is my preferred carry method since it allows the user to grasp, draw, open, and use the knife without having to change his grip on the handle.
This is much faster and more reliable in the heat of a fight.

I hope this gives you some insight into the Tempest design.'

Recently i acquired this Rigid Yukon fixed blade without a sheath, as the previous owner bought it from a forgotten RIGID display case.
Rigid was started by two former Buck Knives employees, Bill Duff & Don Collum who were both supervisor on the Buck assembly line.
The first Rigid knives were made during their lunchbreaks.
This knife is one of the first that was made in the Rigid workshop in California, later the company moved to Arkansas.









The knives were made entirely by hand and have semi-hollow ground blades in 440C steel with a higher hardness than was usual in those days.
The steel can be sharpened to a very keen edge and it also holds that edge for a considerable amount of time.
Production numbers were never very high, but the knives had a good reputation among hunters and collectors alike.

Overall length: 27,0 cm
Blade length: 14,0 cm

Vintage P.Holmberg hunting knife, made in the Swedish city of Eskilstuna.
Pontus Holmberg (1852 – 1893) started his factory in 1876 (Aktiebolaget Pontus Holmberg).
When Pontus died in 1893, the company was first operated by Pontus’ brother Fritiof Holmberg (1860 – 1911) and later by Fritiof’s sons Fritiof Ragnar (1889 – 1916) and Fritiof Ruben (1893 – 1952).
In 1951, the company was sold to Heljestrands industries, and the company produced barrel knives at least until 1954.
The company closed its doors in the early 1960's.

This YouTube clip by a German collector showcases the newer stainless steel version of this model:

https://www.youtube.com/watch?v=rkjCWAqa42o

As the original edge of the knife was rather blunt i gave it a new one, after grinding the old apex flat on the Tormek by using a combination of Rubber Wheels coated with diamond grit to create the new bevels & various Paper Wheels with fine diamond compounds for the finishing steps.
Now photographing shiny metal to resemble accurately what it looks like in real life will always remain difficult (especially with a cheap camera like mine), and this edge is no exception: what at first glance may look like a polished edge is in effect just a polished toothy edge, but one that is easily hairwhittling sharp yet has noticeably more bite than expected.
The new edge is ever so slightly convex and it's apex fits in the 30 degrees inclusive slot of my Tormek WM200 angle guide.
