Just wondering if anybody else that has a contego that has sharpened there's or re-profiled has noticed how acute the angles are.

I just got mine in today and since I despise Factory grinds, I sharpened mine and realized the factory grind was at 15 DPS. That seems really low for a factory blade although I know it is M4, it just seems crazy that Benchmade would grind it at such a low angle

On a side note, this is my first m4 blade and Holy crap does that m4 have an aggressive bite to it. I finished it a 600 grit and a 4m stop and it was cutting free hanging hairs...just nuts, it only took about 15 minutes to get it there...love this stuff

They might go that low of an angle because it's M4. I did my m4 para2 at 12.5dps and it held up relatively well. I changed it to 16dps because I didn't like how wide the bevel looked.

Yea, I hear ya, interestingly enough, the contego seems to have a pretty thin edge geometry because the 15dps bevel is not that wide compared to say a zt 560 I have with a 17dps and it is about twice as wide as the contego
 
Benchmade seems to be one of the few production companies that knows what they're doing when it comes to this. Different steels perform better with edges at different angles. I've noticed over 60+ Benchmades that the edges will be different for D2, 154CM, S30V, 440C, etc.

Imagine that, a knife company that actually pays attention to the edge. Now if we can just get them to make them even.

I believe the first thing I did with my 810 was take it to 13dps. No idea how it came.
I consider 15dps the maximum for m4, and that's about where I keep all the hss knives I use on the job.
