Picked this up at local market today. Appears to be unused. No makers marks other than "MADE IN SHEFFIELD ENGLAND" on the blade. Can anyone provide further info such as useage, age, possible maker etc. Blade is 25cm long.
Looks like a guitar kerfing saw for cutting frets, The handle shape looks like it might be made by PAX? Here's a similar one on Amazon. https://www.amazon.com.au/ALS-Fret-Slotting-Depth-Stop/dp/B077Y6NCR4
A little more searching and I think it's this one. Made by Thomas Flinn Pax, possibly with the adjustable stop made by a third party? https://taytools.com/products/thomas-flinn-pax-taytools-10-guitar-fret-saw-16-tpi
