Boker Ceramic Rigging Knives

I think they have been abused( they have probable been kept in a cockpit locker since they have come off a cruiser racer and the crew obviously do a lot of their splicing themselves . I would oil them since the locks are not stainless they are actually cheap knives 39€ on Amazon they are reasonable sharp but not shaving sharp to be quite frank I would throw them away if I did not know how to sharpen them I charge 16€ a knife(for ceramics ) which is barley enough but if they were done more often they would not be so bad .
I think the value of high tech Dyneema lines that they are used on when splicing warrants throwing them away when they are blunt .
I would use a laminated steel knife and then at the end of each session it takes very little to retouch the edge cutting braid line crucifies a blade and that is just nylon Dyneema is probable twice a heavy on a knife which is why riggers like ceramics but I think this is largely because most of them either don’t know or do not wish to sharpen.
All steel knives need attention try cutting up 10-20Kg of vegetables the knife will need at least couple of passes over a steel or honing . The world just seems to get lazier .
I wouldn’t mind one of these Bokers as a curiosity they are very cheap considering the carbon fibre scales they are not that light in weight the mechanism could have been carbon fibre they have a nice locking action .
I have never managed to get a ceramic to shaving sharp Ken is about the only person I have heard that has achieved this and if the blade was over polished it would not cut the braid line at all I have tried cutting braid line with polished edges and it just does not work even if the knife is shaving sharp.
I do ceramics as an exercise but they are tedious to do I estimate they take about 5 X longer than steel to sharpen I think on the whole most are cheap and they should be binned when blunt.

I quite understand it is hard to say no with someone who you think may bring more business I still find them a challenge but I hate them in use there is no feedback when cutting they seem to be all or nothing I think for many tasks they are dangerous because of this .
It is also a misconception that they are much lighter than steel blades I have a couple of Japanese knives that are probable just as light and cut way better .
I think in England when not dealing with Super Yachts normal people would not be prepared to pay enough to justify sharpening them unless it has some sort of importance like a wedding gift or a hand down.
I will try sharpening my own one on my diamond belt 300 grit and see what happens I cannot imagine that Trizac belts would touch them ; have you any experience with Trizacs re ceramics?
