Sharpening My New 940

I got a 940 about a month ago and used it for some work this past weekend, which put it to the point where I thought "might as well give it it's first sharpening." Since then I have been trying to get it back to hair shaving sharpness. I get it to where it will cut things, it's sharp, and even cuts some hair. But it's not really "shaving" sharp. I know I don't need it to be, but I would just like to get it there. I have a knife from a different company also in s30v that has proven much easier to sharpen: I actually accidentally scraped it against a rock while cutting briars, then against cement while opening a box and it was easy to get back to shaving. Does Benchmade use a different heat treat than its rival(s)? Has anyone else had this with a 940 or Benchmade s30v?

I like Benchmade's heat treat of S30V, seems like every company using the stuff uses a different formula for their knives and comparing will give different numbers. What do you use to sharpen yours? Just curious...many of us send ours up for a nominal fee, but I own an Edge Pro and have no problem keeping the edge I want and after a while that actually saves money.
 
I thought about sending mine in, but I have no trouble with my other knives and thought why not. I don't have a sharpmaker, and my method is crude and kind of embarassing. but I do use ceramic... the bottom of a big ceramic cup. It's absolutely smooth and has worked well with my others though. I then strop with the back of a belt. If an edge is particularly rough I have a two sided stone, but I didn't have to use it on my 940. I know it's not a good system, but it has worked beautifully for other knives.

I'm starting to think it may be partially (at least in the last inch or so of the knife) due to an uneven bevel. The bevel is wider and a different angle on one side than the other and I didn't realize until now.
 
Re do the primary edge. If you are using stones gap spine about the distance of two quarters between spine and stone or just enough to clear the thumb studs and go for a burr then same on the other side. With that done get your secondary edge. Diamond stones work the quickest.
 
Well shoot, maybe it was because I didn't realize the 940 had a slight recurve until right now!

That may not be the reason; Osborne knives that come through BM tend to have a very shallow bevel. 940, 585, 580, 470... I've looked at all of those models in person, they all have it. I actually had my edge backed up for me at a shop, wish I had before and after pictures for you. But, since then, it's been very easy to re-sharpen, never mind getting it to shaving sharp. The difference it made actually convinced the manager of the store to do the same thing to his 585.
 
Yeah, I noticed that as well. Do you think benchmade would do that if I sent it in for sharpening and requested it? If not, could you refer me to the shop you used? (unless it was just local)

There are a couple members here, that do outstanding work, and will probably do it any way you want. Very reasonably priced too
