I have seen several posts on forum members tools, I started my Apprenticeship with the NCB here in the UK, and we were supplied with a complete tool kit (King Dick), with the cost of the tool kit repaid through our weekly wages, the kit was to suit our need to work on mining machinery from 1/4" drive right up to 1" drive Imperial & Metric. sadly over the years they have disappeared, Although i started to build up my own kit from the 80s with the adage buy the best you can afford at the time. Stahlewille being my first choice followed by Snap On or Mac, I know there are several other tool manufacturers I was curious what XS owners own and their preferences
