Very nice , when you can make your own tools it’s one less $ that could go overseas.
And If a part breaks you can fix it or make a new pcs. I think it helps you to do better work all together cause you know if you make a crappy tool it’s going to perform crappy and it will show in your work. Quite a few of my woodworking tools are modifications, or old tools I’ve rehabbed and I’d use them before any of the new stuff that’s out there . I like wood and metal , plastic has very little place for good , durable tools I expect all most all of mine will wind up in my son’s hands one day.
Quality materiels and proper use will ensure that.
