To echo what BC42. The satin stainless steel works really well. It doesn’t have the sticky or gritty feel that the black titanium axis bar lock has on the bugout and bailout. A black oxide or parkerized finish on the stainless steel,axis bar lock will smooth out once the finish is worn off by contact from the blade.
The gritty feel is more in the channel of the liner where the axis lock slides back and forth, not where it contacts the blade. I've only had 1 knife out of 12 that lock stick was so bad that I took it apart to figure it out. Usually, you can rotate the axis lock to find a better spot on the cylinder of the lock.I would polish the gritty feel right out.
