Mystery Tool of the Week – 1 Do YOU know what this tool is called and what was it used for? If you know – put them in the comments. I used it the other day and works great! 7 Comments bloksav on May 15, 2015 at 17:26 My guess is that it is a set for saw blades. Brgds Jonas Reply Michael on May 15, 2015 at 18:21 You would indeed be correct – I are also known as a saw wrest Reply bloksav on May 16, 2015 at 02:50 It looks a lot fancier than the one I use for my saw mill blades, but the principle is the same, I must admit that I am having a lot more problems with the mystery tool No 2 :-) Brgds Jonas Reply Clive Cartledge on February 14, 2016 at 05:46 was led to believe during my carpentry apprenticeship it was to measure the guage of sheet metal Reply Michael on February 15, 2016 at 21:04 Clive, that’s an interesting idea – but this is actually a saw wrest – used to set the saw much like a modern saw set. the different slots cater for different saw thicknesses, so in that respect it is a metal gauge. I am curious as to what a carpenter was doing gauging sheet metal? Reply Clive Cartledge on February 16, 2016 at 16:34 Hi Michael thank you for your reply, in answer to your Question .In the 60s in a small west Australian town a carpenter would do many tasks. roof sheeting was mainly corrugated iron which although rare did come in different thicknesses we also did on some occasions lay bricks and painted amongst other things. one of these tools I have came from my Grand fathers toolbox which contained a saw set that looks a lot older. Regards Clive Reply Michael on February 16, 2016 at 20:14 That makes perfect sense – I live in a small village in Upstate New York and all the local contractors seems to have a hand in all trades.
