Thumb's and teeth

[gris91]

These small "teeth" that more and more blades got at the back spine for additional thumb grip (or so I've been told), how effective are these? Which knife got the best?


Thanks. Still doing research for my MIL-1 knife.

That all depends. Usually the better they work, the less comfortable they are. There are exceptions. Those on the Sebenza work very well and are comfortable. On the Spyderco Native they are a little on the sharp side. The Camillus EDC is comfortable but somewhat less secure. It's really going to come down to personal preference.

There are many different types of thumb-grip grooves, and each type is built for a specific reason and determined by many factors. Such as -- how much exertion will be put on the thumb ramp, will the user possibly be wearing gloves, how big is the knife, is it a hunter, fighter or chopper, and where will they be located on the knife?

The Camillus EDC's traction cutouts are quite shallow and very slippery. Very rounded-off, they're not sharp at all.

At the other end of the spectrum are my Strider MFS and Buck-Strider folder. Nice deep aggressive cutouts, they're there for more than just show. Your hands won't slip at all when your thumb is on these things.

There's limitations, of course. Your thumb isn't always going to be resting on the thumb rest, especially when you need to grip the knife tightly (try fighting off a hundred cardboard boxes!). In fact I find that only for the jobs requiring control (but less force), I have my thumb up on top. So they're really not all that useful. The other parts of the grip are infinitely more important (to me).

I'm not too sure about a knife made for fighting. Perhaps a psycho ninja knife fighting military killer will gravitate to this thread and enlighten us.
