Bests & Worsts Reviews from Amazon

These are NOT JIS screwdrivers! In fact, if you go to the Hozan Tools website and look up the part numbers, you will find these are listed as Phillips screwdrivers, there is zero reference to JIS screwdrivers in the description for these. Let me put it another way: the modern Phillips tool bits are either machined or ground and made without the old Phillips "curve" to the sides of the flutes that made the Phillips "cam out" on torque. Most new Phillips bits and screwdriver tips are made with straight flutes, so they work as both standard Phillips and JIS screwdrivers. I actually talked to a Vessel Japan representative who told me they no longer make JIS only screwdrivers because their Phillips screwdrivers will also work as JIS. There is no reference to JIS on the Hozan website; they list these screwdrivers as Phillips. BUT, the tips are pressed (these Hozan screwdrivers are the cheaper type so the tips are not ground or machined) with straight flutes. So they will work as both Phillips and JIS. I don't believe there are any real old-style JIS-only screwdrivers or bits made any more and I have bought plenty just to see, screwdrivers that are claimed to be JIS but really aren't. Is this a problem? Not really, because the modern grinds mean that if the manufacturer does a good job, the "Phillips" screwdriver will also work in JIS screws. NOTE: I took detailed measurements and photos and the Hozan screwdrivers appear to be identical to a modern set of straight-fluted Phillips 0, 1 and 2 screwdrivers. Also, these are very basic screwdrivers, with cheap plastic molded handles. They'll work as Phillips screwdrivers, but don't expect Snap-On type quality. Very disappointed that there are apparently no more JIS screwdrivers anywhere, I have purchased bits and screwdrivers that claim to be JIS but aren't. Which tells me that there really isn't any difference after all.
