The Charge is part of a family of tools that we designed as a team. The features that I invented on this platform are the Saftey Interlock (#182) which prevents the knife blades from deploying while the Jaws are out, the Scissors (not shown here) and the Component Locking System (#118).

The goal of the Safety Interlock was to prevent accidental cuts from the knife blade while using the jaws. Basically, when the Jaw opens, the tip of leg #188 is pushed sideways by the ramp (#196) and forces the post (#182) through the frame and then into the thumb hole of the knife blade (#180 previous slide). With the post out, it is impossible to deploy the knife blade until the jaws are once again stowed.

One thing you notice when using the component lock system on this tool is that it has a much lighter force to release the lock, but it also has a much greater locking strength than others with big springs. The key is how the force is managed. The result is a much stronger, more reliable lock.

This is the lock mechansim for the Kick. The spring lock on this model is simply an overcenter lock like on the original PST. The big difference though is the shape of the spring. It is designed to work in the same component lock notch that works with the locking latch on the bigger tools.

The sciccors on the Surge were based on my original design from the Wave except that these are quite a bit more beefy. I was able to cut sheet metal flashing with these and still come back and cut braided fishing line. Patent #7,249,390 and # 7,530,129

For those who follow gardening multi-tools you might recognize this as an earlier version of the Hybrid. Functionally, it is very similar, but this first version was not as sleek as the final version.

Most garden shears have their springs on the outside. To get this tool to fold up, I came up with the method shown, which is to have the spring be a single formed wire captured inside the head of the shears. The combination of material, processing and profile enable this spring to go for a very long time without fatigue.

Here is an exploded view of the inside of the shears. Because the pivot can be disassembled, you could change out the blade with any compatible blade.

This is obviously the final verison of the Hybrid as it went to production. You can see that the styling is much more sleek and appealing than on the first design.
