You get a brand new plane or chisel with the best steel and you sharpen it up enough that you could shave a shadow off of your eyeball and leave no trace. Now for the test. Do your test it on a knarley piece of new lumber or do you do the test on the most perfect board you can find in your stash. Then do you put it away for only perfect pieces or do you put it to work as a regular worker. I started to find myself leaning towards this thinking and had to resist. I just make myself use the great tools that I own and found that they work just fine and are a pleasure to use. No babying for me anymore. How about you?
