Ultra-Sharp Shaves: 15% Diamond Lapping Paste for Straight Razors
Take your shaving routine to the pinnacle of comfort and precision. Our 15% High-Concentration Diamond Lapping Paste** is engineered specifically for serious straight razor enthusiasts and master honers who demand a flawless, laser-sharp edge.

Standard polishing compounds work slowly, but our 15% formulation packs a high volume of premium monocrystalline diamonds per gram. This ensures rapid material removal, clean scratch elimination, and ultra-fast apex refinement without causing heat buildup on your razor steel.

Why Choose 15% Concentration for Straight Razors?

1.  Accelerated Honing: Spend less time on the strop. The high-density diamond structure refines hard vintage carbon steel and modern stainless steels in just a few passes.
2. Perfect Edge Geometry: Designed for micro-stapping on hard substrates like balsa wood or leather-on-acrylic paddles, preventing edge-rounding.
3. Sub-Micron Mirror Finish: Strips away micro-burrs to leave a pristine, frictionless edge that glides effortlessly across the skin, eliminating razor burn.

Razor Micron Application Guide:

1. 1.0 Micron (~14,000 Grit):The ultimate transition step immediately after finishing on synthetic or natural honing stones.
2. 0.5 Micron (~30,000 Grit):** The sweet spot for regular maintenance. Refines the edge for an incredibly smooth, comfortable shave.
3. 0.25 to 0.1 Micron (~60,000 to 250,000 Grit):** Extreme nano-finishing for absolute surgical sharpness and ultimate edge-reflection.

Quick Stropping Instructions:
Apply 2–3 tiny, pinhead-sized dots to a clean, flat balsa wood block or a dedicated paddle strop. Spread evenly. Strop your straight razor spine-first with zero downward pressure—let the 15% diamond concentration do all the work. Wipe the blade thoroughly with rubbing alcohol before your final passes on clean, unpasted leather.

Grain size: Please select from the list 

Diamond concentration: 15% by weight, or 30 ct. (6 gr.) of diamond in 40 gr. bottle. This is the highest concentration, which can be manufactured. 
If you need higher concentration, simply mix required quantity of diamond powder with any lubricant (oil, glycerol, etc.)

Monocrystalline diamond powder.
   Micron diamond powders (grain size below 40 micron)  are monocrystalline by default. Yes. they may be obtained by milling of polycrystalline diamonds, but this hardy makes their crystal structure "poly", read more below. 
   Synthesis of polycrystalline diamonds: monocrystalline powders are pressed in a capsule, which then is exposed to high temperature and high pressure (HTHP synthesis), resulting, for example, in cutting inserts.
   Synthesis of monocrystalline diamonds: graphite powder and catalyst are pressed in a capsule, which then is exposed to high temperature and high pressure (HTHP synthesis). 
   To receive really polycrystalline diamonds  you need to use ultrafine micron powders (0.1/0 micron), obtained on super centrifuges in small amounts, because of high cost and comparatively low demand (e.g. for polishing of mirrors in space industry), so resulting crystals will be real agglomerates. But if you use powder 40 micron to make  polycrystal and then mill it, you will receive powder containing monocrystals 40 micron and finer, but not polycrystalline powder. 
   Milling of polycrystalline diamonds for pastes  does not make sense considering extra work and no benefits. Although defective diamond polycrystals are definitely milled.  Fairy tales about "more cutting surfaces per particle" of  diamond  "micron polycrystal"  were true about spiky diamond mono crystals synthesized on soviet presses long ago in a country far away. Presses, utilized now (American belt presses in South African E6 and Chinese cubic presses elsewhere) do not deploy synthesis profiles to make similar crystals. (Of course there are expensive exceptions :) )
