Don't ever put a PUMA-knife on a high speed sharpening wheel. You will burn the steel and destroy the cutting edge. (fig. 2)
Thin and wedge-shaped blades (fig.. 3)
can be resharpened with PUMA-Arkansas-Oilsstone No. 903576 and PUMA- Sharpening-Oil No. 903579. Put some sharpening oil on your stone. Lay your blade flat on the stone with the cutting edge facing away from you. Then tilt back of the blade up to approx 30 angle. (fig. 4). Push the knife away from you.
Just like you are trying to cut a thin slice of the surface of the stone. Repeat this stroke two or three times. Turn your knife over to the other side of the blade with the cutting edge facing you. Tilt the blade to approx. 30 angle. (Fig. 4) Pull the knife towards you just like you are trying to cut a thin slice of the surface of the stone. Repeat this stroke two or three times. Take the same number of strokes on each side of the blade. (fig. 5 + 6)
BLADES which have been resharpened often and which are dull and round (fig. 7)
should be resharpened on PUMA-Sharpening-Stone No. 90 3578 as follows:
1. Wet stone thoroughly with water and keep surface wet during resharpening process.
2. Start on the coarse, light side of the stone. Put the knife in the right hand and hold blade flat, start rubbing a few strokes right and left against the edge.Turn knife over and rub in the other direction. Always press blade against stone just like you are trying to carve a thin slice of it. If the blade is thin enough a fine burr will be seen on the edge. By rubbing the blade on the sharpening stone damages on the edge will also be removed.
3. This bur has to be removed on the fine, dark side of the stone. Tilt knife approx. 30 to the surface (Fig. 4) and proceed as on the Arkansas Stone above.
