Knife edge problem...

Hey!

While my guitar's drying up, I was looking at the trem for the first time and I saw that one of the knives is totally done for. It has more like a u-shape than a flat sharp (more blunt) edge .
Is it possible to turn this thing around and use the backside of it, with filing that down of course?

Now I know why my Jem always tried to be out of tune . How much are new knives, btw?

I've been to the trem section before and and also read Rich's instructions on how to file them. I know what they're there for...

I'll try to get a picture...

Okay, now I'm f'd. The thing is, I turned around the u-shaped knife and put it back in in order to check, whether this would work once I file it down. But now, I can't even move it anymore! This thing is absolutely stuck. I wanted to take it out to scan it for you guys to see what I mean, now it seems it'll be in there forever. DOn't know what to do, really....

Any suggestions?

I'm really getting tired of all these JEM-related problems. I mean I love this guitar, but it's turning into "the money pit" for me...

Please Help!!

I take it this is an old Jem, the knives have had detents for awhile now that make them tough to come out. I've got a tech article started on how to pull knives just haven't had time to finish it. Get a pair of cutting pliers, the only thing I found that would get enough bite on the knife to work it out.

Yeah, it's an old Jem. The thing is, I tried it with the pliers on my Leatherman and it still didn't move a bit.

I'll have to get some good pliers then.

But, what's striking me as strange: On your site where you show how to file the edges, the left and right pivot points look the same knive-wise. But I just found a site where the right pivot-point looks exactly like mine did, although it's new. I don't get this. Here's a pic
I borrowed from GhesQi J's site. Why does this look different then the one you showed?

I don't even think there's a pic of the curved side in that article

*Cutting* pliers [since you like that so much ] They're not like pliers but have a cutting edge like a pair of wire cutters, just very heavy duty wire cutters.

That right knife edge seen on my site is indeed not worn. It's a spankin' new Lo Pro, never used.
the right knife edge is supposed to look like that.

Okay guys, I can say: woooooooohooooooooo!!!!
A buddy of mine did it. I went to him to ask whether he had some cutting pliers and he tried it himself and: tadaaaaa. Thing's back out again...

Thanks for all your input guys. I really appreciate it!
Btw, how much are new knives anyway?

You never had to buy new ones?

So you think I should just file them then?

Fabe

P.S.: How much are the posts? I think that's the real problem. I read in another post now where someone described the exact same problem I had, with using the whammy and going out of tune. You said it's the posts. How much are they then?

So you nearly butchered your trem because of .. (what's the opposite of knowledge?? My english sucks, I know) ??

I'd say the trem will now never hold the tuning properly, cause you've removed the knife several times, so it's a bit looser than before.

Oh, and check your PM
