Target now sells this little tool. That's where I got mine, yesterday. Only had a chance to open the blister pack today. And when I locked open the little #11 hobby blade
for the very first time, the little ball (pictued above, on the right of the locking mechanism) snapped off and fell down between the lock spring and the bottom of the tool.
I only noticed this, after trying to close the blade; by pushing down on the lock. The nearly microscopic ball was wedged between the lock mechanism and bottom of the tool itself, thus preventing the lock from being released. Taking a small throwing-knife, (a butter-knife with a tip) I was not able to pry the ball loose. But I was able to line it up with the hole it is supposed to protrude from, in the open position. I was then able to fold the blade back into the closed position.
I opened the blade again, and once again had to use the tip of my throwing-knife to re-position the broken ball back under its hole; just to close the blade.
Quality tools don't break the very first time you use them, as they are supposed to be used. My Gerber Artifact broke, the very first time I locked the hobby blade open. Also, in the closed position, I found that the blade can pivot open a bit too easily. Not a good idea to carry this tool loosely in a pocket. Nothing like reaching in, and pulling out a blood-stained finger from your pants-pocket.
I had intended to carry this tool without the hobby blade attached. Thankfully, it does remove easily from the tool, but not too easily that it might fall out unexpectedly. Still, the Cross Driver is sharp enough that I can see it being able to easily poke holes in one's pants-pockets.
Overall:
This tool is a POS (Piece of $#^%). The broken lock for the hobby blade is not a big issue for me, but only because I never intended to keep the blade on the tool. Still, in order for this thing to be a decent tool that one can EDC, you have to use a dremel tool (or a metal file and plenty of elbow grease) to remove the Cross Driver at the top of the tool. And if you need a very small folding blade, you're far better off buying a very small folding knife with a decent lock. (I recommend the Spyderco Ladybug). Definitely best to carry this Gerber tool with the blade removed.
Now I just need to unscew the lock spring from the tool, or get some Krazy Glue to make sure the hobby-blade-handle can't accidentally pivot into the open position.
My advice, save your $$$.
