For me ramping is essential for chunkers and most thinning shears I dont on the small ones or the flat micro edge shears but I would appreciate your take on curved chunkers what you do on the rideline do you just use a archone or how would you deal with a missing rideline at the beginning of the ride next to the pivot especially on the cutter inside curve I really appreciate you sharing your wisdom it has helped me alot along with bonika's videos I've been watching almost every day for 2 years now so thanks

Very nice vidéo

Good information isn't it.

[@simplychristal6526]

If you do not have a Twice As Sharp or Okami Gold, can you chamfer on your flat hone machine?

[@BonikaShears]

YES!!!! Watch this video and tell me if this works for you. kzbin.info/www/bejne/npqbqJSuoNWchaM

I think I radiused out my German shears trying to get a ride line on a DMT DIAMOND STONE (Coarse/extra fine duo stone) how can I repair that. And what grit water stone is that?

[@BonikaShears]

If they are German shears, they may be ruined. Those usually don't have a rideline.

[@mrcreator2]

@@BonikaShears they get a sharp edge on the twice as sharp…but when reaching the middle to tip..they start folding the paper towels.

[@keithtreisch6890]

Can anyone explain the actual backgrind that your cutting your new ride line into around etc. Eventually that needs reground etc . How is that done ?

[@BonikaShears]

Are you talking about the hollow?

[@keithtreisch6890]

@BonikaShears yes. The "hollow grinding " I have assumptions. But. Just curious pro technique on it or moreso the actual wheel for grinding. Would ir be diamond ?

[@alexachtar-zadeh663]

What brand is this sharpener?

[@BonikaShears]

Jim uses a variety of machines and brands. We sell the Scimech which is available at bonika.com.

[@flyfishbrad]

What stone is he using?

[@BonikaShears]

It looks like a 6000 or 5000 grit Shapton Professional Stone. I think at the Sharpeners Jam this last week-end he had switched to a 2000 grit stone.

[@flyfishbrad]

@@BonikaShears thanks Bonnie. I just put my order through for the 1000/4000 Kitayama you guys have. Good talking with you last week.

[@bucko1948]
