Gerber Obsidian

I have the fine edge version of this knife. It is a solid knife. The quality seems good so far after a year of use. The blade holds a good edge. The lock is a nice safety feature and it can be locked in the open or closed position. Its intent is to keep knife blade from accidentally closing on you while in use which it does.

The tools (bottle opener, philips/slotted screw drivers, and file) seem to work fine in a pinch.

When using the bottle opener I suggest placing your index finger along the top of the knife to increase leverage. It's kinda rough opening a bottle w/o doing this.

I do wish that there was some type of lock for the tools. If you place any substantial amount of pressure downwards while utilizing the screwdrivers it will close on you if you are not careful.

Over all it works well. Other than the above issues it serves my purposes. I have to be fair. It's a knife not a multi-tool.
