The same diamond whetstone as the DC3, but instead of the leather pouch, it is sold with a double-sided pressure-sensitive adhesive tape which allows you to fasten it on any flat spot e.g. our zytel sheaths. The VHB 5925F tape is extremely strong and will harden permanently over 24hrs. In size, the D3t will fit the F1, S1, H1 and the A1 zytel sheath. Diamond on one side, tape on the other. This one-sided whetstone does not have a ceramic component.
The advantage of these materials, although they get worn, will still keep their flat shape: this is important when you sharpen your knife. And since these materials are the hardest we know of, they will sharpen any steel, even these extremely hard powder steels. You don't need any lubrication for these stone but now and then you should consider cleaning them with warm water and liquid soap. The stone might feel coarse from the start but will become smoother/better after some use.
How to use your whetstone:
Use no oil or water.
Start by laying the blade flat on the stone, raise the blade spine approx. the thickness of the blade, and start moving the knife in circular motions.
The ink trick:
Colour the edge with a felt-tip pen. You can check your progress in sharpening the knife by observing where the colour is removed.
How to check the sharpness:
To check the sharpness of your knife, pull the edge very lighly on your finger nail. If it cuts, the knife is certainly sharp enough for most tasks.
