Does it work on serrated knives and scissors?

Yes. It has a dedicated slot for serrated edges and scissors, separate from the straight-blade slots.

Will the suction base hold on any counter?

It grips best on smooth, non-porous surfaces like tile or polished stone. Textured or uneven surfaces weaken the hold.

How often should I use the coarse slot?

Use the tungsten steel slot only to reset a dull edge, then finish with the ceramic slot. Frequent coarse use wears blades down faster.

Can it sharpen ceramic or serrated-only knives?

It is built for steel straight, serrated and scissor blades. Ceramic knives need a diamond sharpener instead.

Does it need water or oil?

No. It is a dry manual sharpener; wipe the blades and the unit after use.

Our take on the GigBu 3-in-1 Kitchen Knife Sharpener with Suction Cup Base

The GigBu 3-in-1 is a manual sharpener with three slots: tungsten steel for coarse grinding, ceramic for fine honing, and a slot for serrated blades and scissors. A suction-cup base locks it to a counter so you can sharpen one-handed. It suits home cooks who want a quick touch-up without stones or a powered sharpener. Against electric sharpeners it is simpler and quieter but removes metal faster on the coarse slot and gives less control than a whetstone.
