I don't know about anyone else, but I always feel just a tad guilty buying a new or new-to-me tool to replace (or duplicate) one I already have. I still do it, but I second guess myself:
* "Did you really need the two japanese dozuki saws? You already have LV backsaws."
* "Did you really need that vintage #3 plane? You already have a WR #3."
* "Did you really need those JET parallel clamps - you already have plenty of F-clamps in that size?"
* "Do you really need those Ashley Isles chisels - you have a good set of Marples blue handles and oh by the way why isn't it sufficient to buy just the Narex bench chisels?"
You get the idea. So, today I decided to just look my addiction in the eye and put up the following sign in my shop .......
"For me, woodworking is really four related hobbies:
1. Making nice furniture
2. Building an efficient, effective and pleasant shop over time
3. Making tools when I can
4. Trying out new or new-to-me tools and techniques"
Now I have an excuse - it's my hobby to test out different tools.
How about you?
