Me he decidido a abrir este hilo porque no he encontrado mucha información acerca de cómo afilar un kamisori desde cero y creo que estaría muy bien conocer las rutinas de los maestros.
He encontrado varios vídeos, el primero es éste:
Aquí gssixgun pone cinta en el lomo de la navaja y usa piedras sintéticas.
Para crear el bisel actúa cómo si de una navaja normal se tratara (ratio 1:1) y una vez que está hecho cambia a 7:1 y otras variaciones según va subiendo el grit.
Éste es un vídeo de aframestokio afilando con naturales y sintéticas:
Aquí refrescan el filo con sintéticas Naniwa 8k y 12k con un ratio 3:1
Esta es la rutina que usa el propietario de japanese-razor:
Shapton 1000 glass stone: Bevel set and honing
30 strokes on a canvas strop - removes the burr. If you struggle with step 1 in terms of it takes you too long, try this step after 3 to 5 minutes. It can often make all the difference and speedily move you on to step 3 without ‘rubbing your razor away’
Series of natural Japanese stones and Nagura (3)
Nakayama Koppa Asagi Level 5 whetstone with Asano Tenjou Nagura slurry: Blade polishing - this is optional dependent upon the results I achieve with the previous stages as recently have discivered that super hard does not always equal super sharp/polished
Chromium oxide impregnated balsa strop: balsa stropping - optional
Canvas strop (Kamisori respond extremely well on these) - absolutely essential
Leather strop: final step in the blade sharpening process- I use 2 strops, one on rougher leather and the final stage on very soft/smooth
I then shave test each and then sterilise one more time in Barbicide. I then wrap in anti-corrosion paper, stamp and store in an air/water tight Peli container.
Here are some really useful tips I am happy to pass on:
Honing Tip: When I get to step 3 I often hold the stone in my hand as think I get a much closer connection between the razor and stone - you need to be careful as you could cut yourself, though I never have hence it can’t be that dangerous!
Honing Tip: Do not spend more time on the lower grits i.e. 1000 than you do on the higher. If a bevel needs to be created then you need to spend time on the 1000 grit. In all other cases I usually spend more time per stone, the higher the grit/Nagura/harder the stone, I go to.
Canvas Strop: A good (or old) rough canvas strop is one of my favourite tools for sharpening as has saved me hours - they really are invaluable not only to create an edge for the first time but to maintain one also. If no canvas available, denim stuck to a piece of wood is every bit as good.
Si encuentro más información la iré subiendo y por supuesto cualquier aportación será bien recibida.
Un saludo!
