What is PostKnife?

PostKnife is a subscription sharpening service that delivers freshly sharpened knives every two weeks.

How It Works


Your fresh knives arrive in the mail. Gather the used PostKnife knives to send back to us for sharpening.


Carefully remove the fresh knives from the sleeves. Insert the used knives into the sleeves and put them in the box. 


Apply the mailing label and seal the box with the tape. Send the used knives back to us in the next day’s mail.

What’s in

Our Unique Edge

Knife sharpening has been our family's trade for four generations. Using methods our ancestors brought from the Dolomite Alps region of Italy, we sharpen knives by hand with a water-cooled grindstone, giving the edge a superior shape and finish that will last.

What our Customers are saying

When you’re managing a restaurant there are a lot of moving parts. PostKnife gives us one less thing to think about. The knives always show up, they’re always sharp and up to our standards; it’s what we need to create quality food and really good products for our customers.

Allison Sandbeck - Owner/Operator of Kickapoo Coffee Cafe (Viroqua, WI)

Since we've been using this service I greatly appreciate not having to worry about making sure my knives are always sharp and ready to go. Plus it's a very simple process. By the time the set of knives I’m using gets dull, my new sharp set is in the mailbox waiting for me.

Kayla Marie - Owner/Operator of Chef Kayla Marie LLC, Food Consultant, Caterer (Mount Pleasant, WI)

Loving the knives. I used one of the chef knives to bang out prep for a party of 150 the other night. I swear it cut an hour off my prep time.

Benefits of Sharp Knives


Sharp edges mean fewer and less severe accidents, with fewer workers comp claims and worker time lost.


Workers can accomplish more, meaning your restaurant can handle rushes more efficiently so you can serve more people.


Knife rental is cheaper than owning and maintaining your own knives, with better results, allowing your staff to focus on the food.
