My local 'pusher' still had new 610/615's... I can look again, if you like, F.M.B..
I know folks who have owned Sebbies - and sold them. As stated, some folks just go through knives - searching. Sadly, I acquire... for future comparison, of course... or is it wanton knife-gluttony? That said, I really have acquired some nice BM's this year (That just doesn't sound good...). I keep noticing what's in my pocket... not the Snody's... or the Skirmish or Rukus or their mini's... but that 710 D2. Quite a utilitarian knife - and very well made, too.
Re BM's and sharpening - like on a fixed angle device such as a Sharpmaker. The BM's are hand sharpened at the factory - their bevels vary - sometimes widely. Reshaping with the basic Sharpmaker - and D2, for example - will seem like a new career. Persevere - clean the 'files' often - and where the manual said 20 pulls, think a hundred plus - with several file cleanings interspersed, too. You'll get there.

PS While a Sebbie is still a dream here, word has it that Santa got me a deal on a Buck 172 Mayo TNT... hurry up Christmas morning!
