We compared two 3-stage electric knife sharpeners: the Worksky Electric Knife Sharpener and the SHARPAL 198H Electric Sharpener.
What we looked at
Sharpening method, blade compatibility, and price.
The verdict
If you want the lower price on a 3-stage diamond sharpener that also handles ceramic and high-carbon steel blades, the Worksky is the value pick at £35.99. If you would rather pay £14.00 more for simultaneous both-blade grinding, quieter operation and a 3-year warranty, the SHARPAL 198H is the alternative, at £49.99.
A £35.99 3-stage sharpener that also handles ceramic blades.
A £49.99 sharpener with simultaneous dual-blade grinding and a 3-year warranty.
