The Work Sharp Guided Sharpening System is a benchtop diamond plate sharpener. It is built around Pivot Response technology. The plate holder tilts side to side, so the abrasive follows the curve of the blade.
Most guided sharpeners force the blade to follow a straight guide instead. It shipped with 320 and 600 grit diamond plates, a multi grit ceramic hone, and 17 and 20 degree angle guides.
It is not the same tool as the Guided Field Sharpener, a compact portable unit. It is also not the Precision Adjust, which clamps the blade. Work Sharp now lists the Guided Sharpening System as retired, so this page explains what it was, how it worked, and which current models fill the gap.
What made the Work Sharp Guided Sharpening System different
Most guided sharpeners hold the blade still. An abrasive moves across it at a fixed angle. Some clamp the blade and swing an arm through a set arc instead.
The Work Sharp Guided Sharpening System flipped that setup. The knife stayed in your hand and moved across a stationary diamond plate. The plate holder itself pivoted to track the curve of the edge.
Work Sharp built the whole design around that pivot, which is why the company called it Pivot Response.
The base held either the 320 grit coarse plate or the 600 grit fine plate. A ceramic rod handled a final polish pass. Angle guides locked the blade at 17 or 20 degrees for the plates, and 25 degrees for the rod.
A detailed independent comparison flagged that fixed 25 degree rod angle as a minor nitpick. The reviewer preferred something closer to 22 or 23 degrees for the rod.
Guided Sharpening System vs Field Sharpener vs Precision Adjust
The naming overlap between Work Sharp’s guided products causes real confusion. Here is what actually separated them.
The Guided Sharpening System was a benchtop unit rated for blades up to about six inches. It offered 17 and 20 degree wedge adjustable guides.
The Guided Field Sharpener is a compact version built for outdoor use. It has a fixed 20 degree guide and a shorter working length, better suited to blades around four inches. The Guided Field Sharpener written up on its own page goes deeper into that model’s real world use.
The Precision Adjust skips the pivoting plate concept entirely. It clamps the spine of the knife and runs a guided abrasive arm across the edge. That trades the freehand feel for a more mechanically locked angle, and our dedicated look at the Precision Adjust covers setup and angle range in detail.
| Model | Mechanism | Angle guides | Best for | |
|---|---|---|---|---|
| Guided Sharpening System | Pivoting plate, freehand stroke | 17 and 20 degree | Now retired | |
| Guided Field Sharpener | Fixed plate, built in guide | 20 degree | Portable, closest current relative | |
| Precision Adjust | Blade clamp, guided arm | Adjustable | Locked in consistent angles | Price |
| Sharp Pebble 1000/6000 | Freehand waterstone | None built in | Traditional stone work | Price |
What it sharpened well, and what it struggled with
Owner reports on the Guided Sharpening System were generally positive on capability. One owner review described restoring an extremely dull knife to a working edge. The same owner reported clean results on curved blades, straight blades, and serrations.
That review called the process straightforward to learn. It also noted the machine takes some practice before results turn consistent.
A separate independent comparison flagged real technique requirements. The diamond plates need dry sharpening or water only, never oil or honing fluid. Lighter pressure works better than most people instinctively apply.
That same source noted the benchtop working surface limits how efficiently you can work a longer blade. You move the knife across a fixed plate length, not through an open belt.
Where the Guided Sharpening System fits now that it is retired
As of this writing, Work Sharp lists the Guided Sharpening System as retired and out of stock. The official product page offers a notify me option instead of a buy button. Work Sharp has not published a discontinuation date.
Listings for the discontinued Work Sharp Guided Sharpening System may still turn up through third party sellers, though current stock is not something we could confirm. For anyone shopping new, Work Sharp’s current lineup covers the same ground two different ways.
Work Sharp Guided Field Sharpener
Closest Current Match
Compact diamond plate design | built in 20 degree guide | pocket sized
This is the closest thing Work Sharp still sells to the old benchtop unit’s core idea. A fixed diamond plate pairs with a built in angle guide, minus the pivoting base. It trades some of the bench unit’s blade length capacity for a size that fits in a pack or a glovebox.
Pros
- Small enough for a bag or truck console
- No clamp setup or assembly before use
- Diamond plates cut fast on dull edges
Cons
- Fixed 20 degree angle only, no adjustment
- Shorter plate length suits smaller blades better
Work Sharp Precision Adjust
Best for Adjustable Angles
Clamp and guided arm | adjustable angle | benchtop
The Precision Adjust answers a different complaint than the retired unit ever solved. It gives control over the exact sharpening angle, rather than a couple of fixed presets. It is pitched as an affordable, controlled option for home sharpening.
Pros
- Angle is adjustable, not preset
- Blade clamp removes freehand guesswork
- Handles pocket and kitchen knives
Cons
- Clamp setup takes longer than a pivoting plate
- Built for the bench, not for a pack
Mistakes to avoid if you find a used or new old stock unit
Do not sharpen with any fluid other than water on the diamond plates. Reviewer guidance for this style of Work Sharp sharpener is dry use or water only.
Do not press hard expecting faster results. One detailed review found lighter pressure worked better than instinct suggested. Diamond abrasive cuts on contact rather than needing force behind it.
Do not expect the fixed 25 degree ceramic rod guide to match every knife’s existing edge angle. Treat the rod as a light touch up step, not a full regrind tool. That matters most if your blade was originally set narrower, so measure the edge angle you already have before leaning on the rod.
The bottom line: the Work Sharp Guided Sharpening System was a genuinely clever benchtop design. It is retired now, and no longer sold new by Work Sharp. If you want the closest current equivalent in size and simplicity, the Guided Field Sharpener is the natural successor.
If you actually want an adjustable angle rather than a couple of fixed presets, the Precision Adjust is the better replacement.
Frequently asked questions
Is the Work Sharp Guided Sharpening System still sold new?
No. Work Sharp lists it as retired and out of stock on its official site. Only a notify me option sits where a buy button used to be.
What angles did it sharpen at?
The diamond plates used 17 or 20 degree guides. The included ceramic rod used a fixed 25 degree guide for touch ups.
Can I still buy replacement plates for it?
Yes. The 320 and 600 grit diamond plates used in the Guided Sharpening System are still sold as standalone parts. The base unit itself is retired, but the plates are not.
What is the difference between the Guided Sharpening System and the Guided Field Sharpener?
The Guided Sharpening System was a benchtop unit with a pivoting plate holder and a 17 or 20 degree guide choice. The Guided Field Sharpener is a smaller, portable unit with one fixed 20 degree guide and no pivoting base.
Does it work on serrated knives?
Owner reports describe successful results on serrations, along with curved and straight blade sections. Serrations generally take more patience with any diamond plate sharpener.
What liquid should I use on the diamond plates?
Water only, or no fluid at all. Reviewer guidance for this sharpener style warns against oil or other honing fluids on the diamond surface.
