Here's my newest addition, arrived in the mail yesterday. It's not perfect -- the Delrin covers are a bit scratched up (doesn't really show in these photos), there's a tiny bit of up-and-down play in the lock up, and the edge had an impressively large ding from hitting the backspring -- but the price was reasonable, and as far as I could tell it hadn't been sharpened since it left GEC, so even after sharpening out the ding, it still has just about all the life left in the blade that it had when it was new (which is more than I can say for other 'user' GECs I've come across with bad sharpening jobs that had to be remedied).
This is my first #99. I like the size (I guess I expected it to be a little bigger than it is). I'm curious if the blade rapping the backspring is a common occurrence with these, or maybe with GEC's lockbacks in general? The only other GEC LB I have is a #72, and it hits the spring as well if you snap it shut (though only a little at this point, and it probably won't after a couple more sharpenings).
Honestly, I haven't seen a blade-rap ding as impressive as the one that was on this #99 when I got it. It was
deep, and you can even see a gouge on the backspring if you look down in the blade well. After sharpening it out, I let the knife close in its own from about 45° open, and it dinged the edge again. I sharpened that one out as well and will probably just leave it as is for now, and try to remember to close it gently. (I know I could sharpen it enough so that won't hit the backspring, and I'm sure I will eventually, but it seems unnecessary to take away more steel right now. Might as well get some use out of it first.)
