My only BM folder is a five plus year old 551 in 440C. It was dull when new, although I liked it's Axis Lock. I've got two S30V Natives - wow! They are smaller - but what quality - and what shavers right out of the box. I finally had to re-edge my EDC Native last summer - on my Spydie Sharpmaker. It was a lot faster than re-edging that Grip. It's smaller size makes it a better pocket carry, too.
I recently added an S30V Kershaw Blur to my collection. My older Blurs, pre-dating that Grip, are 440A - and needed somewhat frequent re-sharpening. They seem just as stout - maybe more so - than the Grip - and fit my hand well. The S30V Blur runs $75-$90 mail order, the Native is now at the lower end of that range. I am partial to S30V.
Of course, my all time favorite handful of pocket folder is a Buck 110. The $25 420HC variant from Wally World is a must have for everyone's collection. The 'Alaskan Guide' 110 in S30V - only from Cabela's - runs $70 - what a knife! Bass Pro, another special only from them, has it in CPM154, too - for $75. Leave me deserted somewhere with only a pocket knife - I'll want a 110.

PS My only other BM is my 201 Activator + in D2. Brand new, it would only cut butter if you had a Zippo lighter to heat it with first. Sad - nice knives, but 0 for 2 for useable blades 'out of the box'.
