The ruggedly built Chef’sChoice® Sportsman Diamond Hone® Knife Sharpener Xtreme™ 317 was developed specifically with the outdoor enthusiast in mind. It is the ultimate sharpening solution for applying hairsplitting sharp edges to virtually all knives, including the heavier, thicker hunting, pocket and tactical knives. The advanced Xtreme™ knife guide system is optimized for accurate control of sharpening angles on thick and thin blades. Eliminating all guesswork, it ensures uniformly sharp edges from tip to bolster on even the thickest of knives. Guides hold blade at precise combined 20˚ angle.
Using two sharpening stages, the Xtreme™ 317 applies a double-bevel, arch-shaped edge that is stronger and more durable than conventional edges. Stage 1 uses 100% diamond abrasives for sharpening and honing and Stage 2 finishes the edge using flexible stropping/polishing disks. This two stage process results in a microscopically flawless polished edge that is superbly sharp and parallel to none!
The Xtreme™ 317 quickly and easily sharpens both straight edge and serrated blades as well as double-sided and single-sided style knives. It’s ideal for sharpening sports, tactical, household and pocket knives. Two year limited warranty. Designed, engineered and assembled in the U.S.
“It sharpened knives so dull they couldn't cut butter! All with razor sharp edges that are holding their sharpness with use! I was especially impressed with the ability to sharpen serrated knives! I am one happy customer!”
– Larry R., MN
Sharpness plus Strength: The Chef's Choice Knife Sharpener Difference
Three key features make the Chef's Choice sharpener the World's Best diamond electric knife sharpener.
Chef's Choice knife sharpeners feature diamond-impregnated cutting surfaces. Diamond cuts fast and smooth, is incredibly durable, and because it runs cool, it doesn't draw the temper from knife edges.
All Chef's Choice knife sharpener models incorporate patented guide systems. Other machines may fail to sharpen properly and can even damage your knives. The Chef's Choice knife sharpener guides produce great results every time.
Most important of all is the multi-stage bevel. Conventional hollow grinding, seen in figure A, creates a weak edge that flexes (figure B) and is subject to cracking and breaking. Chef's Choice knife sharpeners create super-honed edges that are much stronger than the hollow grind because the edge has far greater support. With the Chef's Choice knife sharpener, your fine cutlery is sharpened for peak performance, and at the same time it's protected against needless damage.
