Increasing the surface area of the edge

[blade2015]

Hello everyone,

I have a question and I hope I am asking it correctly. I am curious how everyone has such a "large" polish edged. What I mean is the bevel is much wider than mine. I have a 940-1 with the factory grind which is now sharpened to a mirror finish. However it is quite small compared to everyone else's I am seeing. how would I go about increasing the area that shows the mirror finish?

The height of the secondary bevel is determined by thickness behind the edge and sharpening angle. You cant change the TBTE (that's right, I'm making that an acronym) so you need to lower your secondary bevel angle. Depending on the steel, you can go quite a bit thinner than factory and still not compromise the integrity of the edge. Try about 12-15 degrees per side. You will have a larger bevel and (more importantly IMO) increased cutting performance.

First off it is not always advisable to increase the the profile/edge of the knife. A lot of it depends on the blade shape.

You can reprofile a knife edge the same way you sharpen it. Or at least in several sharpening methods. I use a belt sander to reprofile edges and/or a combination of belt and wet stones.

Review the 'sticky' notes in this section for knife sharpening tips and techniques. Practice on a cheap blade. Be patient, take your time.

Thanks for the info. It's s90v so anyway you cut it I would have a job ahead of me to get to that point. Would you say this steel can handle a 30 degree inclusive edge or should I keep my factory 40. Medium use edc(cardboard and box opening mostly with some very light wood work)

It can definitely handle a 30 degree inclusive edge, it will feel like a whole new knife and should be in no danger from those tasks if you take reasonable care of it. Just don't lend it to idiots who want to cut open tin cans with it or chop with it on granite countertops.
