Replacement cartridges will only fit the Premium OmniShavers that were made on or after January of 2019. Our replacement OmniShaver blade cartridge package includes 4 shaving cartridges and 1 cartridge replacement tool.

We can't really answer how long the OmniShaver’s blade edges stay sharp. Although we can confidently say they will outlast all other known shaver’s blades’ edges. If OmniShaver is kept dry and clean between shaves, it stays sharp for an extremely long time. This is because its' blade edges self-straighten and polish (or “strop”) during use.

We’re not promising OmniShaver’s blades will stay sharp forever. But if maintained, they will certainly stay sharp exponentially longer than all other shavers on the market today.

Most other shavers/razors require replacement blades after about a weeks’ worth of shaves, so expect getting over 2 weeks of use is usually considered by most to be a good value.

If your OmniShaver is losing it's sharpness...please try following these instructions:

#1- Soak OmniShaver in hot water for a couple of minutes. Then rinse OmniShaver under hot running water. This should loosen up any clogged on debris. (If successfully cleaned, you should be able to see through the blades to the other side of the OmniShaver).

#2- Pick a 7" to 8" area of skin with no hair, like maybe on the reverse side of your forearm. Now generously lube that area of skin up with hair conditioner. Now take your cleaned OmniShaver and make 25 to 30 fast 5" back and forth strokes over that area of lubricated skin.
#3- Now rinse out OmniShaver and then lubricate your scalp and give shaving another try.

Your blades should be re-sharpened and you should get a great shave.

Replacement blade cartridge kits are now available.

Nicks and/or cuts usually come from successive passes over skin that's been irritated. OmniShaver requires fewer passes and therefor irritates the skin less. Nicks and/or cuts can also come from dull blade edges being pressed harder to shave "one-last-time". OmniShaver’s blades’ self-straighten and self-polish during use, so maintaining it's sharp edges helps to prevent nick and/or cut problems. The most common cause of nicks and/or cuts with traditional shavers are with their blade heads being tilted by a leveraged handle, which creates uneven angles of blade edge attack to the skin. With OmniShaver, the blade head always maintains a parallel downward pressure plane relationship to that of it's cutting surface, making angles of blade edge attack consistent throughout the shave. This makes nicks and/or cuts from gouging less likely.

The Premium OmniShaver is almost three times the weight of the Classic model because of its' triple plated steel shaving head. This new OmniShaver is not only heavier, but it transfers captured heat to the skin's surface as the shave takes place.

Once the triple plated steel shaving head has been warmed up from the hot water, it will retain the heat throughout the shave which provides a soothing feel to the skin and helps to expand the hair follicle size so the blades can deliver as close a shave as possible.
