Zandstra sharpening stone foss duo diamond

1. The grinding block
Dimensions: 250 x 70 x 10 mm
The diamond block consists of 3 parts:
- Plastic block
- 2 removable diamond grinding plates
The removable diamond grinding plates have the following structure:
1200 (10 Micron) Extra Fine
400 (37 Micron) Fine
The plates are firmly and flat on the plastic block via 6 magnets. There is a small recess on the side of the block.
This recess makes it possible to release the plates from the block. This is for cleaning or replacing.

2. Benefits of the FOSS Diamond Block
- Sharpening is faster
- The diamond plates remain flat
- Less burr formation
- Durable in use
- Suitable for all qualities and hardnesses of skating steel
- Easy to keep clean (rinse with water)
- Virtually unbreakable (with normal use)
Unique to the FOSS Diamond Block is the option to easily replace a plate after long-term use.

3. Some advice
- Always use water as a “lubricant”. The diamond then has less wear.
- Pressing hard while sharpening is not wise.
- After grinding, clean the plates thoroughly with water and store them dry.
Even the finest diamond plate is too coarse for polishing skate blades. We recommend polishing the irons with it

4. Durability (life time) of the diamonds
The diamonds wear out during use. This goes as follows:
1. Initially, the diamonds have a sharp structure
2. This sharpness disappears after 1 or 2 sharpening sessions. The diamond then retains the same structure for a longer period of time.
3. After many grinding cycles (100+), the cutting speed decreases.
