Being a kid of a parent that went through the depression, some of the habit rubbed off on me. One of my Japanese saws (a Dozuki Saw) had damage to a few of the teeth, right where you use them most. So I bought the replacement blade but couldn't bring my self to toss the old blade as there was a piece of it still good. So, I cut it down and made a mini saw. Thinking it major use will be for starting cuts in hard to reach areas. Also kinda cool to have tiny saw. Anyway, this is about 1.5-2 hrs of effort. Probability could do more to finish it nicer but, this will work for my needs.
