Hello all.

Just received this unusual hand held knurling tool from Ebay.

It's quite neat and works well. Never seen one like it but it may be something from industry.

I did a test piece shown above it and the diamond pattern was very tidy.

I like that yes

Maybe designed by someone who owned a Pipe-Cutter ?

Interesting that there are apparently three knurling wheels; also that you were able to traverse by hand.

A set of these with the knurl type indicated by the knurling on the handle would be good.

It moved smoothly along the work with just a little sideways pressure. The only thing I cant fathom is the cylindrical boss on the end with the two wheels. Looks like it could be a mounting lug but I'm not sure.

Obviously knurling pressure is varied by squeezing the pistol grip.

I agree with Michael G, isn't that just a nice piece of tooling?

Michael many thanks for the link. There it is still in production.

I'm a bit confused, not being of a horological persuasion, as to why such a tool is manufactured by a precision clock and watch tool maker.

Its capacity is 3 to 25mm which seems quite big for a watch maker. The spare Knurls also look quite coarse.

Is this just for horology or a general tool? Seems everything else on their site is just for watch making.

I have one and it is used generally in Instrument work right up to the collets.

It was part of the inventory for the Service Dept. at Leica and I aquired it on close down of a satellite workshop that was not making money, I asked what I should do with the kit and was told to dump it!

Yes, into my tool box

Plasma, one use in clock making that I can think of would be knurled clock case feet but seems kind of expensive for that.

Certainly on the large side for making watch parts

... but just right for making parts for watchmaking tools

Perhaps they originally made them for use in-house, and then realised that there was a market.

Clive's comment would appear to support this hypothesis.
