What's my line. / What is this tool / item used for-- panel had to guess.

Anybody used one of these?

Yes….when I was in the SS

Yup, but I won’t give it away too soon!

Norvin some sort of extraction tool?

Baldrick

Nope, not extraction.

OK I’ll bite…..well I was going to until I realised that’s a little hooked spike and there is a groove in the block…so no I’m not gonna guess because I have absolutely no idea.,

Norvin has that been fabri-cobbled together or is that how it comes?

Baldrick

It’s as it comes, made by a very well known company.

Norvin does is split/cut something? That little hook looks pretty sharp and the square part has a recess in the side of it

No, it’s not for splitting or cutting. That bit is sharp but it’s not needed for its function.

The pin is fixed to the leg. The centre knurled bit rotates but that is not important, the centre bit is spring loaded and moves back and forth.

Elcarajillo

Near enough. It’s a pair of lockwire pliers. Used for twisting stainless wire to lock fasteners in place. Often used in racing where regulations stipulate the sump plugs etc have to be wired to stop them unfastening to prevent oil being dumped on the track, but also useful for stopping bits of classic bikes vibrating off. Made by Loctite.

Elcarajillo Yup - it’s a wire twister. You grip the wire in the jaws which lock shut, then pull back the large knurled knob that spins the tool and the wires.

Norvin, you were too quick for me. :-)

Is it some kind of sine calculator, or some other compound angle plotter or calculator? Where do you get all this weird stuff! :-)

An adjustable template for marking out… something.
