How do you sharpen them ?

They self sharpen as you use them. Use at about a 45 degree tilt angle; apply color; rotate/spin a few degrees and color; continue until you have used all 360 degrees of the crayon diameter and you should have a new point. Works for me. I have never tried a regular crayon sharpener, but the primary (for the big crayons) one with the larger insert hole might work.

Keep them clean use very little WD40. They cut through just about anything. Haven't had to sharpen them yet.

They can be sharpened with a flat sharping stone using a little pressure, taking your time (Few mins.) you will be able to feel the difference from when you started. Keep the blade flat on stone using slight circular motion.

I use the Lansky sharpening system and sharpen it by sections. I've also used the diamond edge "steel" to rought it in before I finished it. Works great for me!

I don't think you can sharpen these blades. They don't come out of the housing and the blades can't be separated.

We use a ceramic knife sharpener. They do get dull but carry a pretty good edge. I would recommend these to you. My wife loves them.

Set the blade on the slicer to open fully so that the sharpening wheel fits behind the blade. Advance the carriage toward the blade but do not have it touch. The blade should contact the wheel in the middle of the "grit". Turn on the slider and advance the sharpener until it touches the blade. The sharpening wheel should turn. Keep the sharpener and blade in contact with medium pressure for about 10 seconds and pull sharpener back from the blade. To remove the burr on the blade, position the sharpener so that the pad is near the sharpened blade. Turn on the slicer and engage the pad by pushing the "actuator rod" to move the pad against the blade for about 5 seconds. Wash blade with damp sponge.

I've had mine for over 3 years and they are still razor sharp. You could possibly take it to a butcher to sharpen it for you. Or buy one of those at home knife sharpening machine.

No they can't be sharpened. Even if they could be it might not be worth it to sharpen them. Might be the same amount of money to just buy new ones.

D2 steel is too hard to be sharpened with a whetstone, you need to use either diamond sharpeners or ceramic crock sticks work well,

I don't think you can sharpen them, we ordered new ones from the manufacturer.

I'm not really sure. I've had mine for about 8 months and they're still sharp. But i am going out on a limb and saying yes. But not a auto sharpener. I'd use a stone

you have to sharpen them, as with all knives. if you buy really expensive Japanese knives, you do not have to sharpen them as often as harder steel holds an edge for much longer than softer western steel.

I have owned this set for a few months now. I have not tried to sharpen them because they are still as sharp as the first day I got them. They do not show sign of dullness. Hope this helps.

They are really sharp to start out with and they last a pretty long while. I'm not sure if they can be sharpened, although if they can't be sharpened I'm sure anyone could just replace the blades on then with new ones. I love these knives. Hope that helped in some way or another.

Very sharp and stay sharp! Yes they can be sharpened using standard method for sharpening or take to a sharpener. How often will depend on usage. When I reviewed these knives they were rated very high. I hope this helps with your decision to buy.

I just have some very sharp knives that I use. Tried using scissors but are not strong enough. Also used tin snips.
