Razor grind again to the perfect sharpness

A razor lives from its perfect sharpness. To grind it successfully, a thorough preparation of grindstone and knife should be done. Cheap whetstones destroy more than they do. Therefore, only high quality products should be used. The grinding process requires rest and time.

Select grindstone

Unlike other blades, a razor comes into direct contact with sensitive skin that has very sensitive nerves. These "blunt" blunt or uneven blades to the user. The grinding and sharpening must therefore be carried out faultlessly, since even the smallest inaccuracies severely restrict the use.

As grindstones only synthetic or natural variants should be used. Two grains should be available. They can be combined on the front and back of a grindstone or consist of two individual stones. For the initial grind, grits between 800 and 1200 should be available. The final touch needs at least a 3000 grit. The so-called Wetzen is not enough.

Cost and care of the grinding stones

Japanese or Chinese waterstones with a gripping tool are the most common and most readily available at moderate prices. For them, acquisition costs of fifty to 150 euros per stone should be calculated. In addition, so-called yellow chunks of Belgian origin, shale and the Thuringian Eschersteine ​​are popular with professionals.

Water grindstones are a purchase for life and should be kept in good condition by good care. Before the first use, it must be checked whether the grindstone has a flat surface. This can be controlled by placing it on a mirror surface or a glass plate. If the stone is not completely flat on the control surface, it must be dressed.

Wet sandpaper is spread on the smooth control surface and watered so that it sucks. When it is sucked in smoothly, the surface of the grindstone is pulled in a circular motion over the sandpaper. The grain size of the wet sandpaper should be roughly the grit size with the tolerance of about 500.

How to grind your razor perfectly

  • Grinding stone 800 to 1200 grit
  • Grinding stone from 3000 grit
  • rubbing marks
  • Waterproof felt pen
  • Magnifying glass with twenty to fifty times magnification
  • scissors
  • Leather or paste belt
  • Non-slip underlay for the waterstone
  • Adhesive or insulating tape
  • If necessary, wet sandpaper for dressing before first use
  • water

1. Mask off the blade

First, glue the unfolded blade on both sides of the thighs so that only the surfaces to be sanded remain open. This will prevent too much metal from being removed during later grinding.

2. Check and pre-grind the blade

Use a magnifying glass to precisely control the edge of your razor. If you come across any cracks, eruptions or other coarse blade interruptions, you may need to pre-machine them with 500-0000 grit wet sandpaper.

3. Water the waterstone

Depending on the type of your water stone, you can water it for up to a quarter of an hour. Ideally, follow the manufacturer's instructions. There must be no air bubbles on the surface of the grindstone. For the main cut you need first the coarser grit (800s to 1200s)

4. Mark the blade

Color the entire blade surface you are going to sand with a dark waterproof marker on both sides. This paint application gives you control later, whether you have sanded the entire blade evenly.

5. Grind first side

Place the knife on the non-slip and watered whetstone at the presumed blade angle. Grind against the blade only with movements. "Push" the blade away from the body over the whetstone. After reaching the end of the grindstone, put it back in front. Do not sand in a pulling direction. For the first cut you should plan about twenty thrusts.

6. Renew taping

Depending on the wear of the adhesive tape, renew it if necessary. It protects the overall blade from excessive metal removal. You may also be able to make a second dyeing with even removal of the felt pen color.

7. Sand second side

Turn the razor over and repeat the sanding in the same way as you did the first sanding. Check in between times with the magnifying glass whether your grinding angle fits and the grinding evenly removes.

8. Fine grinding

Change the water whetstone or turn it over. Carry out the fine sanding on the grit of at least 3000 with about ten draws.

9. leathers

Finally, you need to peel your now sharpened razor about a hundred times on smooth leather or a so-called paste belt. It must always be pulled so that the blade only hits the side of the leather. Instead of "leathering" you can also use very fine natural stones, the finishing stones with grain sizes from 8000 onwards.

10. sharpness control

If you guide your razor along the blade at any hairy part of the body, the hair should now be able to "fall" easily.

Tips & Tricks

When grinding your razor, it also depends on your sensitivity. Not all instruction steps, especially in terms of quantities, are always required exactly. When grinding you should always keep an eye on your individual progress. Work slowly and thoroughly.
