Mail-In Sharpening

Send us your knives.

We offer mail-in sharpening services for your dull or damaged knives. Follow these simple instructions before sending your knives to us.

 

Step 1

Take a photo of your knives.

With a ruler to scale, take a photo of the knives that you would like sharpened. If there is any chipping or damage, make sure that it is clearly visible.

 

Step 2

Email us.

After reviewing our services and attaching any photos, send an email to info@seisukeknife.com. We will review your request before following up with an estimate. 

Once we have agreed upon the services, you will receive an invoice for the total cost of the services and return shipping.

 

Step 3

Complete your invoice.

You will receive a confirmation email once your invoice has been paid. Don't send us your knives until the payment for the sharpening has been completed.

 

Step 4

Pack and ship your knives.

Once you have completed your invoice, send your knives to Seisuke Knife at 1526 NE Alberta St, Portland OR 97211.

 

Step 5

Check your email.

You can expect to hear from us at various points of the service. If we have any questions or need clarification, we may have to put your knives aside until we hear back.

Once your knives have been sharpened and their services complete, you will receive an email with tracking information. From your doorstep and back again, it's difficult to give an estimate for how long it will be.

 

Step 6

Unpack your knives very carefully.

Before getting too excited, remember that you are opening a package with very sharp knives. They are wrapped securely, but we don't want any fingers or hands getting sliced.

Once they have been safely unpacked, we hope you enjoy using your newly sharpened knives. If you are unsatisfied with the sharpness, don't hesitate to reach out.

Frequently asked questions

No, we sharpen just about anything that's made of steel and has an edge. Whether it's a fancy Japanese knife or a knife from the grocery store, we'd be happy to sharpen it for you.

It doesn't even have to be a knife; gardening shears, scissors and even small swords are accepted. That said, we can't sharpen everything. Knives with small serrations, ones made from ceramic, and scissors that don't come apart - these are all edged tools that we are unable to accept.

Normally, we estimate about a week for your knife to be sharpened.

Our sharpening team is small and we have the dual blessing and burden of having many people wanting our services. Rather than rush our services, we want to ensure each knife is sharpened properly and well.

We assess each knife that comes in and explain which service we'd recommend and why. The service that your knife needs is going to vary depending on certain factors, like steel quality.

Our Kaiten service is great for nearly all knives, giving a sturdy and sharp edge.

If your knife is made from a high quality steel, we recommend either our Nakato or Shiage services. Typically, we reserve the Shiage sharpening for knives made from High Carbon or Powdered Japanese steels.
