Believe me there is a big difference to some (not me) and some people get mad about it. Lynn is absolutely correct as it applies to carving.
However, some grumpy carpenters who aren't carvers use it as means of measurement. Especially for doors, windows and making shims for the jams. Plane (most wood removed), whittle, and shave (least amount). Of course the rest of the world does not recognize this unique language and the precise accuracy of this scientific mathematics. Kind of like the difference between a dash, pinch and touch of something in the kitchen.
Now that you've guessed how I've spent my free time.
