My first Benchmade was a 551 Grip - in 440C. I was in awe of that AXIS lock, seemingly nearly as secure as a lockback, like my favorite Buck 110. Certainly more secure than my Kershaw liner/frame locks (Blur, Leek, Scallion), which I have still never had a problem with, other than the 440A steel which dulled more quickly than my Bucks' 420HC. That 551 was over seven years ago, I think... and being my most expensive pocket knife - and having such a name - I never tried the edge. It wouldn't cut butter without being heated. Even edge - just dull. My Bucks, Kershaws, & Spyderco's were all shavers as delivered.
The Grip is well made - the AXIS lock is a great selling point. It is necessarily thick, to contain the steel subframes. Great grip feel - but not a great user for me - it sat in a drawer for years. Sharp now, it is a keeper. I remove clips, for bottom of pocket carry, so I can't speak to it's side of pocket wear. Opening near AXIS lock is wide but small - likely not a pocket change collector like other knives. It has a grippy texture - great for serious work, as are the thumb notches. The 440C takes a while to re-edge, but keeps said edge well. Thicker blade than my new 635BK, thinner than the 630 - my only two other BMs for comparison. If sharp out of the box, a decent value.
Nearly five years after buying it, I thought - try Benchmade again. I ordered a 201 Activator+ fb - the plus was simple - get out your stones, it came the same way as that Grip - dull, but very even. Eventually, I had gotten a Spydie Sharpmaker - and both of my original BMs are razors now - and fantastic. Also, I doubled my BM collection this month with both a mini and regular Skirmish - both delivered new as razors. I'll buy more Benchmades now - as I can afford them. I'm at the other end of the college experience - a retired college professor - actually, an instructor (No research/paper requirement - just teaching!). Teacher's Retirement doesn't go that far - Sebenzas and Busses are a dream now.
Cultivate those gf's - ten years of marriage resulted in that 635BK as an anniversary gift from her. Keeper - her and the knife!
