Re: Sharpening & Calculating Ideal Bevel Height (trigometry!)

The reason I prefer Spyderco stones over others is that, if I spray a little liquid on the stone, I get a suction feel when I have the blade at the correct angle. I remember reading somewhere that we have the ability to feel incredibly tiny differences in surfaces (say, an offset in a pair of butte...

Re: Sharpening & Calculating Ideal Bevel Height (trigometry!)

A laser "goniometer" is the only accurate/precise measurement I've seen. http://bessex.com/forum/showthread.php?tid=338 Here's a DIY version I've had good success with. Here's the way I think about sharpening accuracy: Actual precision of angle makes little difference. Repeatability makes ...

Re: Why are seki city spydercos so different?

Many years back, when Cold Steel used to have their knives made in Japan, the Zytel/FRN, the back locks, the integral Zytel/FRN pocket clips, and the blades of their early Voyager folders (which were AUS-8, like several of Spyderco's blades were in the '90s) were of a similar build quality to Spyde...

Re: AI, Sp AI derco knife. Let’s see what AI does with Spyderco designs

I think ergonomic design is actually a really interesting area to use AI. Human designers can and do work with constraints they learn and categorize over the course of a career; AI can learn those same parameters very quickly and infer novel designs based on them. For example, if you taught a neural...

Re: Straight Razor from Spyderco

There are a few places that make stainless razors, but they are not as popular as non-stainless razors. People say they can't see any difference in performance, but one maker I know says that the carbon steels are best. All of my razors are non-stainless. I will note, however, that 13C26/AEB-L are ...

Re: G10 Sanding And Polishing

One thing to note is that the back spring is now very slightly proud of the g10, but not a lot and it doesn't bother me. Just be careful how much material you remove, especially during the dremel stage. One trick to help control how much you're removing is to paint edges. Use something waterproof t...

Re: Spyderco Safety Razor?
