In reply to Pyreneenemec:
Bought two MOACs and a CLOG Hex from Tanky at the end of 67. All three have had many rethreads but are still getting used. (Even more than ever because people like the way the fit snugly in hand cracks where other shapes tend to rock and roll!) The originals had rounded corners and slightly curved faces with a ground rough finish. After about 1972 the second lot came out which had very sharp corners, very flat smooth sides and were rubbish!
I also still use my original Snowden Mouldings orange handled curver axe from who knows when (Tanky could sell me anything, and when he did it seemed to be good and last!)Also have a pair of cloggers that see occasional use, as they allow my big hands to use them with big old gloves on.
Maybe I still use the old stuff because I am a typical tight Yorkshireman who works on the value for money principle, i.e. if I paid for it, it must last me until the end of my days!
