Lap Sharp LS-200 Sharpener Lacks Features But Offers Wet and Dry Grinding
posted on by
Lap Sharp LS 200 Grinder Sharpener Lap Sharp's LS-2000 grinder offers solid, basic wet and dry sharpening, but lacks features.

While basically simple, this machine laps, grinds and hones all manner of tools — chisels, plane irons, scrapers, carving and turning tools, even jointer and planer knives. Only three tool-guiding jigs are required to handle all of this sharpening. Among its unique features are a deadman-type foot switch, reversible rotation and both wet and dry operation.

Spraying water on a lap sharp abrasive While the Lap Sharp sharpener offers basic dry grinding but also offers a spray bottle to add water to the abrasive.

The foot switch frees your hands so you can hold the tool in position on the abrasive while you switch on the power. This is especially helpful in lapping the backs of tools.

Sharpening a microbevel on the The coarse and fine abrasive pads produce a slightly different bevel angle, allowing you to create a microbevel on your blades along fine grit disks.

Sharpening knives and other double-bevel tools is where reversibility is important. Sharpen one bevel with the platter spinning counterclockwise, then reverse the rotation to hit the second bevel.

The machine comes with four machined aluminum disks, each with a different abrasive applied — 120-, 80-, 35- and 10-micron (approximately equivalent to 120-, 220-, 320- and 800-grit). An optional polishing pack has three additional disks with 5-, 3- and 1-micron abrasives for honing and polishing a cutting tool. (One micron is roughly equivalent to 8,000 grit.)

Although you can use the Lap Sharp dry, the basic kit includes a spray bottle for wetting the abrasive. The water cools the tool and carries away the swarf, which extends the abrasive life.

To a purist, many of these features are critical. If “good enough” is a concept repellent to you, this is your power sharpener. You can lap tool backs flat, not just flat enough. You get the benefit of wet sharpening without the waterpark mess.

Grinding single and double beveled edges Reversing the motor on the abrasive disk allows you to grind your double-bevel edged tools as well.

The basic machine doesn’t come with any tool holders or guides, so if you get it, you must do it all freehand. Three tool guide packages are available. The primary guide accessory, for straightedged tools, adds $80 to the price. A guide for curved-edge tools costs $120, and the jointer-planer knife jig costs a whopping $250, as of 2008.
