Clauss Knife and Shear Sharpener

Comments about Clauss ExtremEdge V2 Knife & Shear Sharpener:

I received the Clauss Knife and Shear Sharpener to review. I have to say its wonderful. The bottom has a rubber bottom to hold in place while you sharpen your knives. I have a set of knives that were so very dull, once I sharpened one knive I went onto the entire set. Now I was just about ready to buy a new set of knives, not needing to now. This sharpener works like a dream come true. I recommend this sharpener to everyone. Easy to use as well.

This is very easy to use, compact so it's easy to take with you and it really does a good job at sharpening knifes and also works on scissors.


OK, but not great

Comments about Clauss ExtremEdge V2 Knife & Shear Sharpener:

The greatest strong point of the Clauss Knife and Shear Sharpener is that it will attach firmly to a kitchen counter or a smooth work table without damaging the surface or requiring clamping it in place. This is a great convenience, especially for larger items like shears. Otherwise, it is just another pair of carbide "sharpening" blades set at a fixed angle. I did not attempt to measure the angle because it really doesn't matter whether the angle of this sharpener matches the proper angle of the blade you are trying to sharpen or whether it matches your preferred angle. Like any carbide V-style sharpener, this tool is fine for sharpening a really bad blade or taking out nicks from the blade of a knife that has been abused. It does an adequate job on most household scissors or shears. With a gentle hand you can even use it to sharpen a kitchen carving knife. BUT this is NOT a tool for getting a fine edge on a good knife. For a really fine edge on a good knife, you need to be able to adjust the sharpening angle to match the design of the knife (or you will have to take off enough metal to create a new edge with a new angle). For a V-style sharpener you need both the carbide cutter blades to take off metal to set the basic profile of the blade AND carbide rods to finish the process. This sharpener has only the carbide cutters. For most casual users, this sharpener will be adequate to put a "cutting edge" on many household blades -- most users will use too much force which will result in a somewhat wavy edge on the blade, almost a microscopic set of serrations - this is great if you just need your everyday pocket knife to be able to cut rope or cord or want your kitchen shears to disjoint a chicken - which is all most users really need a countertop sharpener to do. It is certainly better than a coarse stone "sharpener," especially the electric ones. At around $20 in stores, this is a bit pricey for what it can do, but the convenience and safety of a sharpener that mounts firmly to a countertop then easily detaches to toss in a drawer might justify the cost for a lot of people who just want something to sharpen their kitchen knives and other household cutting tools.


Very convenient

Best Edge in a long time!

Received this about 3 weeks ago, it stays securely in place allowing a straight pull on snags to dimple the edge. Used it to sharpen my knife set and they have not been this sharp since new.

Cartridge Comparison Guide
  • Cartridge Types
  • Ink & Toner Basics
  • Number of Pages & Shelf Life
Cartridge Type
Genuine or OEM (Original) Cartridges Remanufactured Cartridges Compatible Cartridges
Description OEM stands for original equipment manufacturer, meaning the cartridge was made by the same company that made your printer. Original brand cartridges are very reliable and sometimes the only option if your printer is new to market or uncommon. Remanufactured ink is a genuine brand cartridge that has gone through one cycle of use. After use, the cartridge is recycled, acquired by a remanufacturing facility and put through a rigorous professional refurbishing process. During the refurbishing process the cartridge is disassembled, thoroughly cleaned and tested for quality. It's then carefully refilled, tested again and brought back to life. Buying remanufactured prevents one less cartridge from ending up in a landfill. A compatible cartridge is a brand new ink cartridge built by a manufacturer other than your printer. It's like buying the generic version of the genuine brand. Most are uniquely designed to differentiate from genuine cartridges. Despite any structural difference you may notice, the cartridge will still fit in your machine and print a full yield, just like the original brand.
Price Factors Many printer manufacturers follow the razor-and-blades business model which may result in higher priced genuine cartridges. Remanufactured ink is much cheaper than the original brand ink. It's far more cost effective to refurbish a previously used cartridge than create a new OEM from scratch. Compatible ink is much cheaper than the original brand. Compatible suppliers don't have to worry about the additional costs that hinder OEMs like new printers or firmware, which lets them keep prices low.
Quality Original cartridges work extremely well and are covered under a warranty by the printer manufacturer High quality remanufactured ink will match the quality of the original, but not all remanufactured ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results. High quality compatible ink will match the quality of the original, but not all compatible ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results.
What's the difference between ink and toner cartridges?
Ink Cartridges Toner Cartridges
Printer Type Work with inkjet printers Work with laser printers
Material Liquid ink Dry powder
How it works Inkjet printers use a series of nozzles that spray tiny drops of ink directly on the print suface Laser toner printers use static electricity and heat to bond dry toner powder to a page
Commonly used by Casual home users, small business and photographers Large businesses and schools
Number of Pages You Can Print A cartridge's page yield is the estimated number of pages you can print. Page yield is based on 5% page coverage. This means that the quoted page yield is based upon printed pages where only 5% of the page has been imprinted with ink. For example, a short memo has approximately 5% coverage. If you have a cartridge that has a yield of 500 pages, it can print 500 pages of that short memo. If you are printing letters, photos or graphics, your coverage will vary greatly and your page yield will drop significantly.
Cartridge Warranty and Shelf Life Most ink and toner cartridges include a warranty or "best by" date on their box. Remanufactured and compatible ink cartridges can last 12-18 months unopened, and toner cartridges can last up to 3 years.
Cartridge Care and Storage Only open a cartridge when you need it. Opened cartridges will eventually dry out, especially if the protective tape or clip has been removed. If you have an open ink cartridge around and would like to try and prevent it from drying out, place it nozzle side up in a plastic airtight tub. If your cartridge came with protective tape or a clip reapply both before storing. Place a damp cloth or paper towel in the tub, next to the cartridge and keep it stored in a cool, dark place.
