With all the threads about them, there has been a considerable increase in interest in Tosuke razors. I've been getting many PMs so here's some information.
Background:
There are razors actually made by Tosuke that have the blue Tosuke handles AND Tosuke's name on the blade. There are razors made by other sword smiths that have the blue Tosuke handles but they have the name of the other sword smith on the blade. In other words, they weren't actually made by Tosuke; they were made by someone else who just happens to be using his handles. The point is that not every razor with a blue Tosuke handle was actually made by Master Tosuke. They sell for the same price and are of comparable quality. However, you should know that they aren't the same. There are numerous threads in the Straight Razors forum here and on SRP if you want further detail. (For the sake of clarity, I'll refer to razors made by Tosuke as "Tosuke" razors and razors made by other sword smiths as "Tosuke-handled" razors.)
That being said, both the Tosuke and the Tosuke-handled razors are in short order. Most supplies have run dry. Most of the few razors remaining are not of great quality. Many of them were neglected, used, or damaged razors that are for sale only because there will be no replacement or replenishment of stock - until now...
Source:
I just gained a source for new Tosuke-handled razors. There is one shop in all of Japan that has started to make these razors. I know everyone has been saying: you can't get them anymore; they're no longer made; there's no interest for them in Japan. Hogwash!

Since Tosuke passed away, these will obviously be made by someone else. I know this is just my opinion but I believe these newly-made razors are of better quality than the ones that were made in the past. They are flawless actually. They come in two different sizes: 165 mm long (50 mm blade) and 155 long (47 mm blade).
Availability:
Unfortunately, there will be a 2.5-month wait for new orders because the shop is processing one
very large order. Please don't ask me to remind you about the razors 2 months from now. If you're still interested, it is up to you to send me a PM 2 months from now.
Pricing:
I have sold the older razors for $120 shipped, then $140 shipped, then $145 shipped, and finally, for $165 shipped. My prices changed as the Japanese shops increased their prices to meet the higher demand. These new razors are even more expensive. Even the wooden box for them is an extra $10 USD. The shorter razor will be for $180+ shipped and the longer razor for $205+ shipped.

I know this is a lot. If you think I'm price gouging, by all means, send me a PM and I will be more than happy to explain how I reached my prices.
