The great thing about knives is just how many minor changes and innovations there are. Sure, we know about the biggies like creation of the pocket clip by Spyderco’s Sal Glesser or the Reeve Integral Lock, but what about the smaller things?
For example, if you’ve bought a Spyderco with a lockback mechanism in the past few years, you’ve undoubtedly used something called the Boye Dent.
But just what is the Boye Dent?
Here it is.

The Boye Dent is a very minor addition that’s infiltrated modern lockback knives from Spyderco. It is essentially a scallop-shaped recess in the release bar of the lockback or mid lock.
What is the Purpose of the Boye Dent?
The Boye Dent was pioneered by knifemaker David Boye, who is now known for designing boating knives. On his site, it says that the dent is for “preventing accidental disengagement of the blade when the handle is gripped tightly.”

Essentially, when you put the palm of your hand against the release bar, there is less material there to accidentally disengage the knife.
