I have 3 types of tools in my shop.
1) tools that I need.
2) tools that shorten the time it takes to something. I can do with out them but it's nice to have them anyway.
3) tools I just had to have because some one told me I just had to have them. These set in a box under my bench.
You too will have all 3 sets of tools in time. You will find that some tools can be used to do more than "the book" says it does.
Good knives, good stamps, good mauls or mallets and the best finish tools you can get. I have 350 or 400 different stamps and use maybe 30 or 35 of them a lot but I have used every stamp I own at one time or another. Some becaused I needed it and some because it just made things go smoother. I don't know if this helps or not. But I am a better to have it and not need it than need it and not have it kinda guy.
