I bought these because of the cheap starter set. I was originally looking at a US made Kodiak set but couldn't afford the price. Anyway, I figured that since I'm still in my early years as a gunsmith I'd start with a cheaper set and if I wear these or break them I can probably afford a better set and won't use well , prefer to learn . I say buy them if you are in the same situation as me or if you are an amateur mechanic working in your garage, if you are a professional mechanic I doubt youβ¦
