Benchmade was getting quite a reputation for sending out dull blades the last couple of years. It was brought up on their forum and they responded and promised to address the issue. In my experience the last few I've bought have been pretty sharp. They look to be using a jig of some sort as the last couple I've bought ( 275 Adams in D2, and the Contego in CPM M4) have been even on both sides all the way to the tip, and able to shave arm hairs without scraping. This is plenty good for production, heavy use EDC type knives. A couple of years ago, starting with my Rukus I got a few that seemed to not have the final edge put on it at all.
The TSEK, M390 581 Barrage, and on have been pretty good so the change for me came around that time. Before that in my experience was hit and miss ( 530 Pardue, LFT in CPM M4 fairly poor finish overall, 710 limited ed., Osborne M4 Limited Ed. were all at least dull to very dull) Good to recent excellent all around were the D2 mini grip, TSEK ( both of them), and a few more I don't recall.
I don't have any problems buying them and consider the latest 2 ( Adams in D2, and Contego in CPM M4) excellent to near perfect. It seems to me their promise to send out sharper knives is being kept, in the case of my few examples anyways.
