Do they use the same sharpener for knives that are sent in to get treatment? Any pictures? Post by wally » Tue Oct 18, am Wich model is second from left? I usually put as low of a back bevel as I want then put an edge bevel high enough to maintain the sharpness. The low back bevel makes cutting easier and and the higher edge bevel maintains the sharpness longer.

That is my goal. I believe lots of experience went into that decision. Post by Taonari » Mon Jan 09, am I usually reprofile my knives to 40 degrees inclusive for use on my Sharpmaker. Sometimes, though, I will sharpen to 36 degrees inclusive on my Edge Pro. Post by unit » Mon Jan 09, am I like sharpening free hand Taking the edge angle down really low and thinning out the blade can yield some very exciting but delicate results.

Thanks, Ken my real name Post by Ankerson » Mon Jan 09, am Depends on the knife and how it will be used. Most of the time I use 30 degrees inclusive, sometimes 36 Degrees inclusive, 40 degrees inclusive or 24 degrees inclusive.

My Spyderco Videos. Post by Minibear » Mon Jan 09, am 30 degrees, with a 10 degrees kind of backbevel. It hasn't been brought down all the way yet. I'm working on it. My sharpening setup M is a great steel IMO Oops, back on topic. This is a great thread and a good place to learn some things about sharpening.

I will follow this thread. I only use and have the Sharpmaker, so that explains it. I've been very happy with the results and performance.

Post by rjowen » Mon Jan 09, am Hey Rookie! Discuss Spyderco's products and history. Forum rules. So I was wondering how and what they used to sharpen their knives and is this something I can replicate at home. Re: What Spyderco use to sharpen their knife at factory?

You will love it! Dang that would be alot of custom work! I think the final edge was either or grit lightly buffed to remove the burr. Many models are currently sharpened using a robotic jig, and the edges have somehow gotten even better.

If you want to replicate it, you could use a coarser grit diamond stone, and just strop it on some leather to polish it up a bit.

Post by cabfrank » Thu Dec 14, am Maybe a stupid question, but do they disassemble the knives to sharpen them folders?

Would there be a reason to do that if they are sharpened by robot? Last edited by cabfrank on Thu Dec 14, am, edited 1 time in total. New Customer Create an Account. Customer Group Default.

Edge geometry begins with the grind, thickness, and width of the blade and its bevels.

For example, a full-flat-ground blade basically has a triangular cross section, with the spine of the blade being the base of the triangle and the two equal-length flat bevels forming the sides. Narrower blades, thicker blades, and shorter bevels would all affect the geometry of the triangle and increase the angle at the edge somewhat, but it would still be somewhat weak.

Instead, they leave a thicker section of steel near the edge. A narrow secondary bevel is then ground at a steeper angle to create the actual cutting edge. The terminal thickness of the steel adjacent to the cutting edge is also a determining factor in the overall edge geometry of the blade. A full-flat grind with a thin terminal edge thickness creates a very acute angle near the edge and the long, gradual rise of the bevels.

This geometry parts the material being cut with minimal friction and offers excellent cutting performance.
