So, mal wieder was irres 
Die Infos sind ganz aktuell, Gavin gab das OK zur Veröffentlichung.
Ich poste hier mal seine Infos, sobald ich eines der Messer habe, kommen bessere Bilder und ich schreib was zu dem Mechanismus. So ganz vorstellen kann ich mir das nicht
Wer Interesse hat, ein paar Prototypen sind fertig und reserviert. Preis 775 EUR. -> mail an mich.
Hier gibts noch ein kleines Video (330k, Quicktime) -> E.T. Open - Close

Grant and Gavin HAWK - E.T.
E.T. is an acronym for External Toggle, and external toggle describes the locking mechanism of this very unique folding knife. The toggle lock linkage is used in a wide variety of industrial grade equipment wherever long travel, a magnification of force and a positive lock are required in a single mechanism. The most common example may be that of the vise grip style locking pliers, which apply far more force than needed for a knife, but works on the same principle.
A review of the drawings shows how the linkage moves during the transition from open to closed and illustrates how the simple act of gripping the handle insures that the blade will remain locked in the open position. When the blade is open, the three pivot points of the long and short toggle come to rest slightly beyond a straight line, drawn through their centers, thereby preventing the mechanism from feeding backwards. A light torsion spring is positioned around the axis of the rear toggle in such a way as to constantly urge the toggle links into a straight line. The effect of this spring is to propel the blade toward open when opening and to propel the blade toward closed when closing. This same spring also serves to hold the blade closed until needed.
The blade stop is adjustable to insure that blade lock up is not so loose as to allow movement or so tight as to generate excessive force in locking. The drawings show the location of the threaded stop, which is specially treated to prevent unintended movement. A 1/16 allen key can be inserted from the front, when the blade is closed, to fine tune this adjustment. The locking nuts securing the long toggle to both the blade tang and short toggle are also adjustable for correct clearance.
A socket wrench for this purpose is provided on board the handle frame, in the form of a lanyard hole liner, inserted into the lanyard hole from the left side as shown. The wrench is held in place by the free end of the rear torsion spring. To remove the wrench simply press on the small end protruding from the right side which displaces the retaining spring and allows the wrench to be pulled free from the left side as shown. The knurled portion of the wrench serves as a finger grip to turn the lock nuts to the correct setting. The adjustment is correct when the pivot points turn free without drag. Reinserting the wrench from the left side of the lanyard hole allows it to be recaptured by the spring.
The titanium pocket clip is reversible by removing the retaining screw and swinging the pocket clip 90 degrees or until it can be spread apart enough to clear the pocket clip bosses on both sides. The retaining screw is then replaced before removing the screw on the opposite side. The pocket clip can now be reinstalled by reversing the disassembly process. When the blade is closed, the karabiner is in the active mode and can be used to carry the knife by capturing a ring or chord. When the blade is open, the karabiner comes to rest on the floor of a notch cut in the handle frame providing a reliable thumb support while using the knife. The karabiner also serves as a thumb stub when opening the blade either left or right handed.
To unlock the blade for closing it�s only necessary to push on the extreme end of the short toggle to collapse the linkage or to push out on the long toggle/short toggle knee joint (see drawing). If anyone ever thought they would like to own a truly unique folding knife with a very strong lock and a yet unknown number of techniques to open and close the blade, they will not be disappointed with the E.T.
E.T. Specs:
Blade Steel: S30V Rockwell 59-60,subzero quench. Heat treat by Chris Reeve
Handle Frames & Toggle Links: 7075 T6 Aerospace Aluminum - approximately twice the physical properties of the usual 6061 Aluminum.
Phosphor Bronze bushings/washers at all pivot points
Pocket Clip/Karabiner: Titanium
Blade Length: 3.125� Closed Length: 5.0� Overall Length: 8.0�

Wenn ich dran denke, dass die alle Teile selbst basteln, zigmal hintereinander mit geringsten Toleranzen ohne CNC, und sicher wieder in der gleichen Qualität wie die TOADs, will ich nicht wissen, wie lange die fuer so ein Ding brauchen. Wenn die ein bischen schlampern, dann ists keine Finishfrage, da wackelt das ganze Trumm.
