Product Features
- Kai AP-0308 Knife Sharpener
- Diamond whetstone and a ceramic whetstone are combined to restore sharpness in three processes
- Stage 1 – Diamond (grit 270): For very dull knives; coarse stones that restore a blunt edge
- Stage 2 – Ceramic (grit 150): Monthly use on all knives; less aggressive but still coarse for sharpening
- Stage 3 – Ceramic (grit 1000): Daily use to maintain and polish a fine edge.
- Transparent cover to keep the sharpener dirt and dust-free
- Casing can act as a handle for more stability
- Other products are available in the Kai range
- Wipe clean - do not allow sharpener to come in contact with water

Price Matching
We always try to price our products as competitively as possible but do understand there might be times where a High Street competitor is cheaper. We will always endeavour to match their price (including delivery) as long as they have physical stores and provide the same level of professional and personal service. This is something that cannot be replicated by the likes of Amazon which is why we do not price match against them or other mail order only companies.

Important Notice - DHL Delivery
Potters Cookshop is not liable for lost, damaged or stolen parcels if a 'safe space' is specified without a signature being obtained. By stating a safe place customers are therefore taking responsibility prior to receipt.
Important Notice – “Safe Place” Deliveries
If you ask the courier to leave your parcel in a ‘safe place’ and no signature is obtained,
responsibility passes to you once the parcel is marked as delivered. Potters Cookshop
cannot be held liable for loss, theft or damage in these circumstances.
Cancellations / Refused Deliveries
If you cancel or refuse your order after it has been dispatched, we will deduct the delivery cost we have incurred from your refund. This applies even if your order qualified for free delivery (as we still incur a shipping charge).
Delayed Deliveries
Please allow up to 5 working days from dispatch for your parcel to arrive before contacting us. Delivery times are estimates and we do not offer a guaranteed delivery date. During festive seasons and peak periods, deliveries may take slightly longer.
We do not offer a guaranteed delivery date at any point.
