Just got around to cleaning up a couple of knives and checked the notes in my kit on my MK1. I'm going to assume that this is the same blade style/geometry as the MK3??
I think it came with a convex grind, but not sure, I ended up making a 25 degree angle and that works for me. I'm sure some may consider this desecration of the factory grind, but for my abusive day to day use it works. I touch it up with a Gatco fine abrasive and then the ultra fine (looks ceramic) hones about once every 4 to 6 months.
I understand that Benchmade will re-sharpen for a pretty minimal charge, that's an option too. I just prefer to be self sufficent and found this angle to be workable and easily duplicatable.
Sheet Bend: As this reply is a month or so after the post, what did you end up using?
