This little neat book clasp came out yesterday . I would like to straighten it out without snapping it . Has anyone any ideas of the best way . I was thinking some gentle heat ? Hot water or naked flame ? or leave well alone . There is some nice decoration on the otherside .
:thumbsup:

Hot water will do nothing, Paul. That little chap's going to need annealing with a torch, but I've never annealed copper alloy so can't advise on temperature required or colour to heat it to.

I anneal copper alloy the same as silver. The metal looks thin enough to straighten but there are no guarantees as metal composition can change and go brittle with age. You'll lose the patina but some things look better cleaned up.
This has reminded me, I have two different copper alloy items I am going to attempt to straighten, I'll post up the results. Hmm, I might do that now! :D

Well it is a bend rather than a crease! :Thinking:

Paul are you sure its a Book clasp ? I would have to lean more to it being a bent " Clog fastener " myself.
Compare it to some of these .

Yes true ,it could be one of those too, they both have a similar job and have a similar shape to them.Maybe if it is a book clasp the end where two holes was has possibly broken off ?
What would you say `s the approx length of it Paul ? If its over than around 25mm that would probably lean it more to being a book clasp.
