Review on 🔧 Hozan JIS-4 JIS Screwdriver Set (New 3rd. Gen) - Japan Import: Premium Quality Tools for Precision Screwing by Kyle Tebow

These screwdrivers are from Japan, decent quality, good for ordinary plastic handle screwdrivers. They will be strong enough to take apart carburetors probably every day. I bought these after getting very frustrated with stripped screws and reading a few places online that the screws on Japanese carburetors require this type of specially made screwdriver. While this is theoretically true, I'm not sure they are extremely unique. Compared to a household handyman or a Stanley screwdriver, they are very different. But the size 1 and 2 screwdriver bits are almost identical to the PH1 and PH2 bits I got in a cheap Chinese handyman screwdriver set. So not sure what you get here is the best value for money. I've used cheap PH bits with my thump on a set of carburetors and haven't stripped a single bolt. However, they were useful for hard-to-reach small screws. I think the impact part is key because I removed a few bolts that were completely ripped off by others in a lightning strike from the impact.
