If it's tiresome, then shouldn't have kids!
I delight in teaching my lad the correct way of doing things, especially in using hand tools.
I did my apprenticeship when H & S was in its infancy, we used common sense, skill and utmost respect for the tool that was being used, wether it was a small hand file or a 40' long lathe, plus the fact we were shown the most horrendous videos, showing the reprecussions of not doing things correctly and safely.
I still see it today, young lads come in to the business, straight from college, thinking they know it all, and to be truthful, they haven't a clue, accidents waiting to happen!
