View Full Version : Tang too short, what should I do?

I have a band new blade but broke it at the tang by cross threading the hex nut. I've had the blade for over a year now but still havn't decided what to do with it. I don't really want to throw away 70 worth of blade.

The tang is now just a bit too short. There is now about 1/2 of one thread that reaches the hex nut. I use small handles and I don't want to make it any shorter than it is already. Is there any way that I can still use this blade. Has anyone else had this problem?

I could drill out the handle, but I don't think I can drill very deep before wrecking the handle. I could get someone to turn down a hexnut at one end, so I can drill deeper with a smaller diameter. Or I could cut the tang down further and weld an extra bit on the end, will this be strong enough?

or shall I just admit defeat, keep the barrel and tip and throw the rest away.

What do you think?

and if Steve Jackson is about he can probably remember when it happened. I managed to cross thread the nut and Steve provided the muscle to release (break) it, not that we had much choice. It was obviously my fault not his.

Sorry Sparkymark, I don't remember this. Typical you remember glorious triumphs but not abject failure.

Remind me what type of blade this is. If it's a Leon Paul folded pattern then return it to them, since they can put a new tang on and on a newish blade this makes sense.

NOTE!!!! EVERYTHING AFTER THIS POINT REFERS TO REPAIRING A TANG. UNDER NO CIRCUMSTANCES SHOULD THIS OR ANY SIMILAR PROCESS BE ATTEMPTED ON A BLADE BETWEEN TIP AND GUARD. THROW THE BROKEN BITS AWAY. REPAIRS ARE NOT SAFE


I've threaten to weld tang extentions on but have no experience of doing so - I suspect that success would depend on the skill of the welder. On the other hand what have you got to loose? As a guess at the process, I'd set the blade first, then find a local welder, get them to cut the tang well below the portion of the tang that will take nut, and scarfe in a piece of 6 mm studding, left over long to give them something to work with. They will be able to tell you if the repair has a chance of working, and which method of welding has the best chance of success. Oh and as a final thought get them to wrap the forte in a wet cloth in case the heat travels.


As I said before I've never done this so your on your own, I don't see why the joint should fail and even if it does the resulting failure will be relatively safe, you'll probably notice the wobble before failure, and I suspect that if its going to fail the time it will do so is when you (or I ) tighten the handle up.

I need notice of the question as to whether the resulting blade is legal or not.

It's a BF foil blade.

O.K. So do you think the welding option is better than drilling the handle and turning down the hex nut.

If so, : I can get an extra piece of studding from another new blade (as it has to be cut down to a pistol grip). Does anybody here that knows me, also know a nice friendly welder :moon:

If it is a B.F. blade supplied by Leon Paul we no doubt can fix it. Re-thread 12/24 and supply an American nut or weld a new tang and or drill out the handle. If the blade was not supplied by us I am sure the original suppliers will be able to offer a similar level of support!!!!!!!

Doh! guess where it come from (the blade was bought over a year ago before I realised how great LP are (grovel)).
and I'm sure that the supplier can't provide the same level of support. But we already knew that.

As clearly you have seen the light (groveling does help) If you promise not to tell any one else, let me have the blade some time to fix. Barry Paul
