Well, now, aren't we an obsessive-compulsive bunch!
I mean, holy crap! These are production knives meant for use, not custom made display knives. Yeah they cost a lot but everything costs a lot today if it's really good--and Benchmade knives are really good. Slight off centering, cosmetic imperfections in the handle material, slightly asymmetrical blade grinds...none of them affect the functional role of the knife in use. And use is what it's made for, not fondling and playing with and admiring and whining over inconsequential imperfections. If it bothers you that much or it's really badly put together, Benchmade has a good warranty--use it.
I own probably 20 Benchmades out of hundreds of knives. Of those the only one that came with any type of overtly obvious imperfection (that I can recall) was a partially serrated 710. The blade had a bad grind, the serrations were cut too deep and the blade was slightly off center. Some of you would probably have had a fit about it and gone online and berated Benchmade throughout all the internet. But I got it from a dealer for a good discount and I decided to just use the thing. I carried it for several years and beat the hell out of it and it became one of my all time favorite knives. Today it looks like hell but it's as tight as the day I bought it, the blade still is slightly off center but it hasn't changed a nano hair from new and those imperfect serrations are well worn down from frequent sharpening.
Knives are just tools. Use them, don't obsess over them.
