I have never seen one of these before (18.40). What's it called?

Swan neck mortice chisel. I think.

 

[AndyT]

I think it's something he's made for himself. I'm pretty sure commercial swan necked chisels were only in wider sizes, mostly for fitting mortise locks into doors.

I think it could be a Japanese bottom cleaning chisel (stop sniggering at the back :lol: ) aka a Sokozarai-nomi chisel.

Like this one?




I've got the S Form Firmer chisel for carving/cleaning inside the top of an instrument after all the braces have been put on. There isn't room for a flat chisel to do that work.

 

[RogerS]

I've got the top one. Never used. Guess I should sell it.

I use a cheap as chips hook tool used for cleaning out horses hooves. Same idea. Under a pound. Hoof pick: https://www.atlantic-equine.co.uk/colle ... -hoof-pick

Available in any riding shop. Or the river shop.

 

[AndyP]

Adrian, isn’t that just a bent screwdriver?. :shock:

 

[AJB Temple]

Pretty much Andy. They get lost a lot in the shavings and muck, so they need to be cheap. Screwdriver metal is harder I think.

 

[Mike G]

Thanks chaps.

One of these perhaps? I think Mike should invest in one :lol: - Rob

Strange sort of a tool Rob, but not convinced it would be much use for the bottom of a hole, wouldn’t take many sharpenings before it was in need of reforging either. Have I misunderstood?

I believe that these are intended for cutting across the end grain of the tenon in a door when a mortise lock was being fitted ln line with the centre rail. Not a thing that I have ever done, but looking at the old joinery manuals shows this as a common practise when siting a lock. The centre rail being referred to as the lock rail.
Riley’s manual shows this on an illustration on page 259.
I’m sure that they would also serve to clean out the bottom of blind mortises. I don’t thinkI will be rushing out to get one though.

I've got one too. I have used it, but I didn't find it that much more effective than using the mortising chisel to scrape the bottom. It won't, however, mash the end of the mortise like a straight chisel will.

I think these would be most handy in cases where your mortise depth is critical, i.e. you don't want to accidentally blow through the back side. Otherwise it's probably faster to just chop a little deeper.
