Naniwa Gouken Fuji 8K - First Test.
I recently had a chance to get a (like new) Naniwa Gouken Fuji 8K. For what I know it's one of the two made by Naniwa specifically for straight razors.
Despite being very busy at moment, I found some spare time (after more than a week it was @ home) to make a quick first test, just to see how it works...
Used the "usual" Lasso Razor (the one for Nagura tests on Ozuku) that had reecently a quick finish on the Water of Ayr Stone.
Made a little bit of slurry with an 1,5K diamond plate and then, 4 series as follows:
- 20 Full Strokes
- 20 Full Strokes
- 20 X-Strokes
- 20 X-Strokes
Completed the test with 10 Laps on Canvas & 50 Laps on Leather.
I'm not experienced enough to judge the microscopic results, but seems not bad to my eye.
Observation through a 40X Loupe showed a nicely polished bevel.
Blade passed easily the treetop test.
Shave test is scheduled for next Monday, as I wanna understand how it behaves on skin.
Next test will be an Ozuku Suita's slurry finish (to compare to the usual Nagura progressions)
Then I'll Test this 8K after a synt 3K and see how it handles the bevel setter's stria.
Last image is made after the four series described above.

Naniwa Gouken Fuji 8K - Second Test.
Just yesterday (so didn't saw Euclid's last post) I made another test of the Gouken 8K.
First of all, lapped (remember I bought it used and already lapped... so wasn't the first time the stone was lapped) it with 400 and 1K diamond plate.
Used for this test an "Import" marked Solingen razor (11/16" - FH) that I used before to test diamond slurry from my Ozuku Asagi.
The honing sequence was Naniwa Super 3K - Naniwa Gouken 8K (two rounds) - Ozuku Suita's slurry on Ozuku Asagi base. Check images for more info.
After the initial edge killing, treetop test was positive out from the 3K, and always better after each step of the progression.
Today's shave was very good: close and smooth.
Of corse, I'll leave any evaluation on the images to the more experienced. ;)
