how fast does the blade get dull?

I have been using this for at least 2-3 years, it has never dulled. When using these, you must be very careful! They are very sharp. If you use it for vegetables that are too small for the holder, be very careful.

They get gradually duller. Depends on how long you can tolerate to take to shave (and touch up with a blade) before replacing. I was on the same blades for 5 years or so and realized how bad they were when I forgot it on a trip to France and bought a new one there. You can supposedly also sharpen them a bit: http://www.youtube.com/watch?v=qSBX81U1otM

Aloha... it takes a LOT of passes to sharpen the serrated knife, but it does help. Even though I only cut bread with my serrated knife it still got dull, and the sharpener brought it back - but as I said, it takes more time than other blades.

I've never noticed knives getting dull due to my bamboo cutting boards. I have good quality knives and use them everyday on bamboo. For a more qualified opinion, check the internet.

The tip of the blade is sharp, and is a danger if you are not careful. Although I haven't quite experimented with it, the sides are dull and shouldn't pose harm if you're just carrying it around or storing it.

It is very solid never any movement. When one side gets dull just switch the blade around and it's like new.

use the #2 stone. If knife is really dull it may take several passes maybe 6.

Only been using it for a few months for trimming hair and shaving beard. Haven.t noticed any difference in blade sharpness.

depending on how many times you need to run it through, 1 minute or so. If it is really dull, maybe longer.

Yes and no if the blade is very dull it won't sharpen, if the blade is sharp it will maintain the blade. I use a hand file to first shape the edge then I use the sharpener.

When i got mine it was really sharp. but after a few months of use i sharpened it with a sharpener i had around the house. you may need a better sharpener.

No. Pulling the knife in and out of the plastic sheath does not dull it. The knife stays sharp as all get out!!!

Haven't yet had any dulling of the blade-only using it sporadically-knife sharpener service should be able to take care of it

I think they will stay sharp longer than I will need them to. I use it almost everyday and it has been a few months. No dulling at all.

The edge isn't really sharp, the very dull. The tip of the blade is sharp enough to hurt someone. My 10 year old is allowed to swing it in play, but I won't let him run or jump around with it outside (or inside, for that matter).

Sorry I have no idea. I would imagine you are correct that a scissor or knife sharpener would dull the blades.

Not sure Patrick - I wouldn't want you to buy it and find out it fails! I think thicker plastic might make the blade go dull rather quickly? I could be wrong, but I'd err on the side of 'no'.
