brown, I'll go there once for you. A 'gravity knife' was a term in the cross-hairs in Cali.. Not all states had the same response. It was thought to be a dangerous weapon if you could unfold the knife by the use of gravity. i.e. pinch the blade with the tip pointed away and let go of the handle and give it a little flick of the wrist. If the knife opens it's a gravity knife. Thus, Buck began installing a bushing in the blade pivot
that prevented this. This bushing being brass, caused slower movement at the pivot & blade and the paranoid officials were satisfied. DM
Thanks Dave Martin!
This knife flicks open by holding the blade. However, some previous owner has filed down the tang, so the tip is a ~1/8" proud. To solve the proud tip problem, it's been intentionally blunted. I couldn't understand why a previous owner would do this. Plus it is in contrasrt with the rest of the edge, which is quite sharp for a well used 110. The edge is ~90% original, but the scales and bolster show very hard use. I think it must have been modified for a gravity drop opening. Just enough of the tip is gone to make it safe for pocket carry.
Thanks again.
