Looking back, my BMs that came sharp were a 760, 710, 635, 630, 615, 426, & 425. Those that needed a 'touch up' were the 610 & 420. These were all, except the 630 - which was an evil-bay b-i-n, bought new this year at a local B&M pusher. I knew the 610 & 420 were slightly off, but bought them anyway because they were the last ones - and that Sharpmaker had instilled a proper amount of confidence within me. Two years ago, I bought a 201 from a mail order supplier - it's dull D2 was nearly a career to re-edge. Six plus years ago, my 551 came - from that same B&M - as the dullest new knife I had ever purchased new - it's 440C edge would prove to eventually be my greatest challenge. So, two very dull, two needed a touch up, and seven were sharp - out of the box. I have bought more Kershaws - and many more Bucks - with only one that wasn't an armhair shaver. That was the first Buck 850 Bravo I bought my son last year - it's single edged Besh wedge blade in CPM154 was crooked and drug on the liner. The replacement from the mail order store was a shaver. That's one Buck I won't own.
So, dull Benchmades make it out the door - if you doubt this, check it out on the Benchmade forum. They are still worth it - great knives - I have the empty bank account to prove it. You can always send it in for sharpening - or get out the Sharpmaker!

PS BTW, while you can clean up a slightly dulled Buck 110 of 420HC with twenty or so swipes per stage, D2 or 440C or even S30V will take 100+ swipes. Be sure to clean the ceramic triangle files several times during a premium metal blade re-edge. Maybe buy some Alieve - and a wrist brace, too...
