Best Knife Sharpening Services

Properly sharpened kitchen knives are as essential to cooking as the ingredients themselves. Dull kitchen knives are not only ineffective; they are also more dangerous as they are prone to slipping and causing cuts during use. While most home cooks may attempt to sharpen their knives with the honing steel that comes with a basic knife block set, the steel only helps to maintain a sharp edge and won’t actually sharpen a dull one. Sharpening correctly involves using a sharpening stone while understanding the proper technique and angle that your knife needs to achieve the sharpest edge.

While it is possible to do this at home, some self-education is involved in making sure it is done correctly, plus the time and labor required to sharpen all your kitchen knives regularly. Luckily, there are various knife sharpening services, both in-store and remote, that can handle this task. We did the work for you and chose the best knife sharpening services around the country to make sure you are never stuck chopping with a dull knife again.

Founded by fourth-generation knife grinders and now run by the fourth and fifth generations of the family, Carisolo Grinding is based in Wisconsin. It provides both regional delivery and a mail-in sharpening service nationwide. All knives are hand-edged on a water-cooled grindstone by a master grinder and then buffed and honed. Any necessary repairs such as broken tips or chips can also be repaired. In addition to both double- and single-beveled knives, Carisolo can also repair machine blades (i.e. food processor blades).

Pricing is tiered based on the number of knives, starting at $49 for up to five knives and going up to $100 for 17 to 20 knives. All shipping costs are included in the pricing. Customers are asked to select a box size corresponding to the number of knives they plan to send in; Carisolo Grinding will then ship out the box with a return label. Then, customers will send in their knives for sharpening via the U.S. Postal Service. The sharpening itself will be done in one day, but the entire process, including transit time, typically takes about ten days from when an order is placed.

Carisolo Grinding goes beyond sharpening services; the company also offers a cutlery rental program for professional kitchens and maintains a sister company, Post Knife, a sharp knife subscription service.

National kitchenware chain Sur La Table offers in-store knife sharpening services at all of its more than 100 retail locations. Sur La Table was founded during the 1970s, with its first store opening at Pike Place Market in Seattle, Washington. Besides kitchen tools, cooking equipment, and serving ware, retail stores typically offer a full calendar of cooking classes.

At just $5 per knife, Sur La Table will sharpen any standard kitchen knife, including Western and Japanese styles. Note: Serrated ceramic knives and scissors are not accepted. Sur La Table sharpens knives by machine, so the service is not as bespoke as some others, but knives will still be razor-sharp. Knives are typically ready for pick up within 24 hours of dropping off, but this may be longer during peak shopping seasons such as the holidays.

Many of us are familiar with home subscriptions for food products, but what about kitchen tools? Launched in early 2020, Togu Knives has introduced a fresh new subscription concept for home cooks, guaranteeing they will never find themselves without a sharp knife. For $6 per month, you will receive a freshly sharpened pair of knives—a 7-inch Santoku-style, all-purpose, double-beveled knife and a small, 3 1/2-inch paring knife. A new shipment (containing a Santoku and paring knife) will arrive after eight weeks, and you will return the used set. This cycle continues throughout your subscription period. Note: Knives can be returned earlier if they seem dull before the next scheduled shipment, but this scenario is unlikely.

Once an order is placed, Togu will ship the first pair of knives to arrive within three to five days. All shipping is free, and each replacement pair comes with a prepaid shipping label and packaging for easy returns. Togu’s knives are made from durable VG-10 steel (the gold standard when it comes to kitchen knives), making it easy to get a fine edge that lasts longer. After each used knife set is returned, it is refinished, sharpened, cleaned, and sanitized before being sent off to another customer. All sharpening is done by hand on ceramic whetstones, a labor-intensive but precise process.

FAQs

Isn’t a Honing Steel Enough to Keep My Knives Sharp?

A honing steel is not a sharpener. Stainless honing steels are great for maintaining and straightening an edge that is already sharp, but they do not rub away metal to create a sharp, new edge. Sharpening involves actually removing material from the knife’s blade by grinding it against a sharpening stone, sharpening wheel, or a similar tool. Ceramic and diamond steels will take off a small amount of metal to slightly sharpen and perhaps buy you more time between sharpening on a stone, but your knives will still need to get properly sharpened at least once a year.

How Often Should I Sharpen My Knives?

This depends on how often you are using them and what type of maintenance you're doing. If you are using steel to maintain a sharp edge, the knife will stay sharper for longer. Most home cooks will only need to sharpen their knives a few times a year if using the steel to hone in between. The best way to know whether your knives need sharpening is to do a paper test: Firmly hold a sheet of basic copy paper at the top with one hand and draw the blade of your knife down through the paper with the other hand, slicing from the heel to the tip of the blade. If the knife slices easily through the paper, it is sharp and ready to use. If it requires more pushing and tears the paper to cut through, it is likely dull and in need of sharpening.

What Is the Difference Between Western and Japanese Knives?

All knives have a beveled edge, meaning there is a slight angle on the side that runs down the edge. Generally, Western knives are double-beveled, and traditional Japanese knives are single-beveled. Double-beveled means the knife is sharpened on both sides and usually forms a V-shaped edge. Single-beveled means the angle is only created on one side while the other side of the blade is completely straight. Western-style knives are the most common and utilitarian while Japanese knives are designed for precision slicing (i.e. slicing sushi).

While Japanese knives can also be found with double-edge blades, Western knives (also referred to as German-style) are not made with a single bevel. Why does this matter? Double- and single-beveled knives need to be sharpened at different angles, so if you are sharpening knives yourself, you will need to know which you have and how to properly sharpen them.

How We Chose the Best Knife Sharpening Services

The best knife sharpening services were selected by reviewing dozens available nationwide. Multiple factors were considered, including the history of the business, in-house expertise, and types of knives the company can service. Pricing, turnaround time, user experience, and customer reviews were also taken into account.
