This is a one off that I am selling on ebay. it is a prototype for a utilty knife based on the Hole in one chassis. It features a retro screw lock and rough finish on the blade holder. I have been carrying this around for a few months now and am happy with how it performs. I am building a newer prototype with a toggle blade lock.
Both blade and frame have a durable non-reflective bead-blast finish.
“This is not a high-force knife, but a versatile, fun, outdoor knife that is going to last a long time. I’ve used it for everything from opening packages to cooking dinner.”
The design of the knife gives many grip options. The index finger can go through the blade hole, or grasp either the frame finger choil, or even the blade finger choil if greater control is necessary.
Tom also designed a spring-loaded carry carabiner (non-weight-bearing) so you can securely hang the Hole In One on belt loops, D-rings, webbing or lanyards. It also will work as a bottle and jar opener.
The Hole In One’s locking mechanism locks both open and closed. Most important, when the knife is gripped tightly during use, the lock also grips tighter for increased safety.
To open the Hole In One blade, simply press down on the lock release lever, and rotate it to either side. Continue rotating until the lock snaps firmly into place in the open position. This is a fast one-hand operation. Because there is no conventional clip, it is a completely ambidextrous knife.
Tom began with the perimeter frame, which is a single piece of 420J2 stainless steel, formed to fit the hand. He thoughtfully split the frame with swells at the top, bottom and butt to add more comfort without adding weight.
The blade shape was then dictated by the handle shape, which we can only call a “Hitchcock blade.” It has a high flat grind with a gently curved Razor-Sharp edge. The model 5160 single-hole blade is plain for easy cleaning, while the fancy model 5150 receives five lightening holes in the blade spine.
“I began looking at the trend to knives with finger holes, and I also saw an interesting side-opener. I thought that I could integrate the two ideas, and make a much safer, friendlier utility knife in the process.
But it wasn’t as simple or easy as I first thought.”
