I want to give my 2 cents on the Thiers Issard "Bio-Diamond" Sharpening Pastes (set of four) I recently ordered from Classic Shaving.
1. Upon arrival, I was surprised.
It seemed like such a small amount of product for the cost since I was used to the Amplex 5 gram syringes. With what seemed like a small amount of paste, I wasn't sure this was going to go very far.
2. I applied the paste to 4 different modular paddle strops I ordered from Straight Razor Place. The paste is a bugger to apply, only because it comes out of the applicator very slowly (I suppose one needs to be smarter than the applicator). Perhaps it's a safety feature to keep from over application of an expensive product.
3. The paste was applied in very small droplets over the strop surface. A little goes a long way and rubs in quite well. I let the strops dry overnight and reapplied another coat the next day and again allowed them to dry for a day.
4. I used them last night on a vintage 5/8 Henckels hollow ground that was not quite ready for the hone but needed a refreshed edge. I pyramided 5(4,3,2,1)/5 with the 6 and 3 micron, then 1 and 0.25 micron, following with a chromox stropping.
5. The results: WOW !
6. Looking at the strops, I wondered "where did the paste go ??
It did not leave a visible surface coat or glaze like the Amplex pastes do, however, when stropping you can feel the drag and cutting action of the diamond particles and see the resulting color slight color change of metal particles on the strop.
7. My final assessment:
An expensive, yet very good product. A little goes a long way so I predict the amount supplied to last about as long as a 5 gram syringe of Amplex. I have only had one go around with it, but the results are better than I ever had with diamond paste without a messy glaze. Anyone else out there with similiar results ??
