The cutting power of a fixed-blade knife depends partially on how much force the user can put behind the blade. However, the more force someone uses, the higher the risk of potentially dangerous slips.
The folks at Petrified Fish have devised a pretty ingenious, albeit bizarre, way to avoid that risk with the PFH01 Eel fixed-blade knife. They did it by subtracting material from the knife.

Sometimes less is more
The crux of Petrified Fish’s PFH01 Eel lies in the massive finger hole that sits squarely between the handle and blade. Instead of a typical choil (or cutout), the finger hole entirely captures the user’s front digit, making it practically impossible for their hand to slip up the blade’s edge when cutting.
This adds an extra layer of safety and allows the user to exert extra force into their cuts without fear of slipping and possibly cutting themselves. It’s a clever, useful addition, especially for a hard-use outdoor fixed-blade knife.
