As noted in the FAQ, the Philips slots of Japanese camera screws are not ordinary Philips slots. Therefore, ordinary Philips screwdrivers should not be used to service Japanese cameras. JIS Type S screwdrivers should be used instead - they have thinner blades than normal Philips screwdrivers.

These JIS screwdrivers are not easy to find in the US or Canada. I bought a set of 4 made by Moody Tools, called "Pollicis". Granted, I am a pretty heavy user, but they broke very quickly in a few months. They offer lifetime warranty, great, but that only gave me a right to claim. What I really wanted was screwdrivers which last longer to begin with.

Probably, the Japanese are arguably the best to make their own screwdrivers, so I found these JIS screwdrivers from "Hozan Tools" on eBay. When they arrive I will report if they are better constructed than Moody Tools. Hope they will last longer this time.

I couldn't find a set of JIS srecewdriver from any normal retail outlets, so I ordered them on-line. I got a set of 4 Moody Tools "Pollicis" extended reach JIS screwdrivers from http://www.rjrcooltools.com/ $16 including shipping.

After using the Moody Pollicis tools, and have to agree that they are not very good. The shafts are not very strong and can bend in use if you have to apply sort of force on tough screws. They are very disappointing and do not recommend them for converting these lenses -- especially if you encounter a very tight or stubborn screw.

Unfortuantely, Moody's is the brand you usually find here in the US. Teh have another version with removable, thick (standard screwdriver-like) handles (set #58-0719) which might be better. I found the Hozan Tools scrrewdriver on ebay and they seem to have thicker shafts (3mm vs 2.5mm) and the bigger handles, so I think they will be a better choice than the Moody's.

Just got the Hozan Tools JIS screwdrivers yesterday. There are nothing fancy, but they appear very well made. They fit Japanese miniature screws like a groove. It gets the job done and of course that's all that matters. Interestingly, the #0 has a shaft with a larger diameter than Moody Pollicis' #1. But then, the number refers to the tip rather than the shaft diameter, of course. Now, only time can tell if Hozan Tools lives up to my heavy use, but given that there are 2 unhappy customers of Moody Pollicis already, I would recommend Hozan Tools for the time being if only by method of elimination. Like MonoInu mentioned, JIS screwdrivers are very hard to find. Just search for "Hozan" on eBay.

The search for the elusive JIS screwdriver continues, because the ones sold on eBay did not work out either.

The model numbers of the Hozan screwdrivers sold on eBay are D-130-75 and D-140-100. Like I said, the shaft of #0 has a larger diameter than Moody's #1. Apparently, "130" means a shaft diameter of 3.0mm, and 40 means a shaft diameter of 4.0mm. A 3.0mm diameter for #00 is too thick and will get in the way of your work. (4.00mm for a #0 is fine.)

We need instead the models D-170-30 and D-171-30, with a shaft diameter of 2.0mm and 2.5mm respectively, and interestingly the diameters are exactly the screw head diameters of M1.4 and M1.7 JIS low head screws respectively. There is a 4 screwdriver set, D-27. If you prefer longer shafts the model numbers are D-170-75, D-171-75 and D-28 for the set.

These seem to be very common in Asia, but in North America, I found only these two places which carry it.

http://www.neiparts.com/tech_tools/hozan/driver.inc.html

I have not ordered from them yet, but I will. The #0 is on sale for only $1.40 from the first URL (D-140-75), and the #00 is $4.95 (D-170-30).

Hozan model D-61 is a #00 with a 2.0mm shaft diameter and costs only $1.30 from the first URL.

So how has the Hozan model D-61 worked out? I'm searching for a set of screwdrivers to work on some lenses and being based in the US the pickings are slim.

After using D-61 we concluded that it may be a bit too small.

http://www.hozan.co.jp/english/catalog_e/drivers_wrenches/D-61.htm

We have found D-130-75 to be very useful, and D-140-100, too, where you need to apply downward force to prevent screw stripping. These are made very tough and built to last. However, sometimes their shaft are too thick and you may need to additionally get a D-170-75.
