Thread: Diamond lapping film-new source

I order stuff for the laser lab from this place. The shipping is incredibly fast.

I just looked, and they now carry diamond lapping film, not just the aluminum oxide stuff. 6"x6" diamond film for $9 a sheet. You can cut each sheet in two 3x6 pieces. Pretty good price for this stuff.

Buy one sheet of each 6um (4000grit), 3um (8000grit), 1um (16000grit).

$27, for a complete range of grits that will have your highest carbon blades pleading for mercy?? $27???? PU-LEEASE!

"Oooh, but Seraphim, I have this new TI, and it's impossible to get sharp!"

Nope....that TI will sharpen up like a fine Wisconsin cheddar when it meets the diamond film...

"Waaaaah, stainless steel is so difficult to hone...."

Put a cork in it, Mister! There's nothing wrong with the steel, it's simply the limp-wristed hones you've been using up 'til now!

"But....but...but...I just spent $1,200 on a Sukahara natural stone that was quarried from the flanks of Mount Fuji itself by a 117 year old Japanese master!"

Wrong answer: what you now have is a $1,200 doorstop! You can perhaps makeuse of it as a backing plate for your new diamond lapping film, welcome to the 21st century!



If you have any "difficult to hone" razors, this stuff will dope slap that razor into line, pronto! Really fantastic stuff!!! You simply wet out a nice, clean, flat piece of glass (they also sell a nice looking one on their site, but any old piece will suffice...I use a precision granite plate from Woodcraft) and lay the sheet down, then press out the water and the sheet will stay in place via stiction. Then you can use it as you would a normal hone.

It also has a very nice "velvety" feel to it, nothing like the feel of a DMT plate, it leaves a much much smoother scratch pattern as well compared to a DMT. Even the 6um stuff will give you a more even, smoother, material removal than the 3um DMT8EE.


Did I mention it is fantastic stuff?!

Buy some. You, and your razors will thank me...

Of course, it still costs $55 for shipping to Japan...but hey, it's good the option is there!

It appears that there is a Japanese distributor? I know my collegues in Japan get Thorlabs stuff. It's not as cheap as it is here, but tey get it.

Great stuff... subscribed, bookmarked, thanked, and rated. Thanks, Seraphim!

I just ordered some of the alum oxide sheets from here to see how they compare to the diamond. 5um, 3um, 1um, 0.3um

Let us know they it works out. I am planning on getting the diamond sheets for some pain in the a$$ blades (Iwasaki)

The aluminum oxide stuff works just as well, but definitely will not last as long.

Here's the progression at 200x:

5um
3um
1um
0.3um
0.3um "Seriphied" (tm) edge

How's the shave off the 16k diamond film equivalent? Do you do anything to the edge after coming off that 16K film?

I incorporate diamond pastes/sprays both in 1 mic and .5 mic during some honing sessions and don't like the shaves straight off those media. Too harsh.

Sometimes I get weepers if it's too sharp.

Some canvas stropping usually drops it into the comfort zone.

I always thought guys that said that were nuts. While I might still question your sanity, I do believe that statement now.

I got weepers like crazy from using a shavette with a brand new Derby shavette blade. Although using this same blade with a more lubricating soap (Tabac) dramatically reduced the number of weepers than what I got with Pen's Blen cream.
