Hi,

Do you think it is possible to sharpen a carbon composite blade?
I would like to try to make a straight razor blade or a kamisori blade but is it possible
to sharpen the edge like a ceramic blade?
If yes what composite is the best performer for this application?
Carbon, Kevlar, twaron?
Gelcoat or just resin?

Thanks for your help guys.
Kind Regards,
Olivier

Thank you Dravis,

Could you give me more help about the mould?
"You will need to use a mould that will stand up to compressing the edge area of the blade with high pressure. (And vacuum of course)"
How do you apply high pressure and vacuum on the same mould?
I expected to use infusion techniques as shown in EC videos.

"To make something really cool using CF, use a Titanium or stainless foil as the middle layer in the blade.   Such a blade will actually be practically usable .. even if the foil itself can not be hardened."
Would you lay the foil up to the edge of the blade or cut it 3 millimeters before the edge?

Thanks for your help 😀
