What angle does the Smart Sharp sharpen at?

The Smart Sharp sharpens blades to an exact angle of 20 degrees.

If you have previously sharpened your knife on a whetstone or steel then please note that due to the more freehand nature of these methods, the blade angle on your knives may be uneven or outside typical ranges. Therefore, it may take extra time and perseverance initially for your knife to adopt the new angle. Once achieved, continued use of the Smart Sharp will keep your blades at an even 20 degrees and future sharpening will take a fraction of the time.

The Smart Sharp is an all in one sharpener and is not intended to be used in conjunction with other sharpeners or sharpening methods. This is because sharpening angles on other devices may be different.

What knives can be sharpened by the Smart Sharp Knife sharpener?

The Smart Sharp is designed for use with straight edged kitchen knives and wide serrated knives (bread knives) only. When sharpening serrated edged knives please use a light hand pressure only.

Not for use with finely serrated knives, scissors or ceramic bladed knives. We also recommend that the Smart Sharp is not used on specialist Japanese knives - this is due to the much narrower blade angles of these knives.

Can I use the Smart Sharp with other knife sharpeners?

How do I use my Smart Sharp knife sharpener?

First things first

Place your Smart Sharp on a solid flat surface (we recommend using a chopping board to protect your kitchen work surface/table top). Hold the handle firmly to keep the unit steady.

Stage 1 – Prepare

Using light pressure and a nice, smooth motion, pull the knife through slot 1 approx 5 times. The knife should move through the slot easily, you shouldn’t feel too much resistance on this stage.

Stage 2 – Sharpen

Using some additional downwards pressure to your stroke, pull your knife through slot 2 with the same smooth movement, approx 5 times. If you’re sharpening knives for the very first time with you Smart Sharp, repeat this action a few extra times.

TIP - You should feel some resistance on this stage as you pull your knife through. If not, then try pulling the knife through at an increased upwards angle until you feel a definite ‘tug’ as it pulls through. You can also try adding a little more downwards pressure to your stroke too. (This is something you’ll get a feel for over time so you may want to experiment a little at first to get this right!)

Stage 3 – Hone

Using light pressure and a nice, smooth motion, pull the knife through slot 3 approx 5 times. (As with stage 1, the knife should move through the slot easily)

Wipe your knife and test sharpness. If necessary, repeat the process. Knives that are very blunt or that have previously been sharpened by other methods may take a few extra goes to begin with.

Maintenance - Once your knife is sharp, you can maintain its sharpness for longer by using just Stage 3 (Hone) on every other use.  Only use all 3 stages when it feels like your knife needs a full sharpen.

Is the Smart Sharp able to sharpen scissors?

No, the Smart Sharp is not designed for use on scissors. Scissor blades are asymmetrical (the blade is angled on just one side) and have a completely different blade angle, These factors are not compatible with the 20°angles symmetrical slots of the Smart Sharp.
