FAQs

Is it easy to use for beginners?

Yes. The Precision Adjust was designed to be beginner friendly. The guided system holds the knife securely and lets you set a consistent sharpening angle, making it easy to achieve reliable results without any prior sharpening experience.

What should I know about setup and maintenance?

Setup is minimal — assemble the base, insert the abrasive rod, and clamp your knife according to the instructions. For maintenance, brush away metal filings from the abrasives after use and store in a dry place to prevent corrosion. Abrasives wear over time and can be replaced to keep the sharpener performing at its best.

Is it better than other systems like Lansky, Horl, or whetstones?

The Precision Adjust delivers more consistent results with less skill required than freehand whetstones, and without the learning curve of some clamp-style systems. Unlike manual wheel-based sharpeners such as Horl, it provides adjustable angles and multiple abrasive grits in one setup. Which system is best depends on your sharpening style, blade types, and preferred level of control.

What makes this different from the other Precision Adjust models?

The original Precision Adjust suits casual users wanting consistent, guided sharpening with a simple three-abrasive setup. The Elite adds seven abrasives, a leather strop, and a carry case for enthusiasts. The Professional features larger abrasives and a fully metal base and clamp for serious users. The Professional Elite combines the all-metal build with the full Elite abrasive kit including resin-bonded diamond plates, for maximum range and longevity.

Do I need to use oil or water?

No. This sharpener is designed to be used dry. Oil can cause oxidation or rust. If water is introduced, dry the sharpener as quickly as possible to avoid damage.

How do you bench mount the PAJ?

On the bottom of the base, directly under the Work Sharp logo, there are oval ribs you can lightly clamp over. Do not clamp too hard — over-clamping risks breaking the base. Clamping the system down is generally not recommended since the knife is already held rigidly in the sharpener, and bumping it could potentially cause harm.

How long do the abrasives last on the PAJ?

It varies depending on blade condition, steel type, size, and pressure used. In testing, approximately 200–300 sharpenings per set is typical. All abrasives are removable and replaceable, so the sharpener itself won't wear out.

What is the correct motion for sharpening? Is it side-to-side or up and down?

Any motion works — side-to-side, up and down, or a combination. The preference is individual and all methods will produce great results.

How do I unsnap the PAJ from the base?

The connection is a firm snap fit. Push the tab at the rear of the base to release it.

What angles does the PAJ sharpen?

The PAJ sharpens from 15° to 30° in 1° increments.

How should I revitalise the leather on the strop?

A petroleum-based product works best for conditioning the leather strop.
