Is a ceramic knife the lightest per inch while maintaining some utility?
I have a Gerber Ultralight LST on order, but for a longer blade suitable for “extreme picnicking” I chose this ceramic folding “fruit” knife by Cera Inc.
Blade is 9.5cm(3.7″) and total knife weight is 38g(1.36oz). This gives a weight/blade-inch of 0.367oz/in. Not as light as the Gerber LST at 0.3oz/in*, but a more usable blade for my purposes. And if I shaved down the 1cm thick solid plastic handle I could reduce the weight.
The knife looks like a toy with its colored blade, and feels so light in the hand it seems like a harmless prop; but the blade is “7 times” sharper than a steel blade according to the box, and it cuts that way. The box also says do not cut bone or the blade might chip, so it must be brittle.
The blade locks in the closed and open position with a small button on the handle. This is replacing an old Gerber LST of similar size with a teflon handle, at 76g.
I’ll report back after some long-term tesing. Meanwhile, does anyone have experience with ceramic knives, or carry one as a light option?
