SPK04SBK: K04SBK Kitchen Utility Knife


Spyderco's involvement in kitchen knives dates back to the early 1980's and the beginnings of the company’s knife production. After being discontinued a number of years ago, they are now back by popular demand and better than ever. Our current kitchen knives combine all the distinctive features of the originals with an improved handle material that offers increased durability.

The K04 Utility Knife has a 6.5-inch drop-point blade that is ideal for a broad range of kitchen cutting chores, making it the most popular "go-to" knife in many home and commercial kitchens. Like the original version, it features a premium MBS-26 stainless steel blade, ground exceptionally thin and meticulously heat treated for optimal cutting performance. Its durable polypropylene plastic handle is injection molded directly onto the tang of the blade and features a distinctive “stepped” texture pattern that provides exceptional comfort and control during use.

This version of the K04 features a SpyderEdge blade with a unique two-step serration pattern that protects the edge from dulling on cutting boards and black polypropylene handle.

Decent Knife
I've used the knife for only a week or two. It is certainly sharp and cuts fine. I like serrated knives, as this one is, because parts of the knife edge are protected from the dulling impact when the knife hits the cutting board or other surface you are cutting on. At 6.5 inches, this knife is not quite long enough to cut a head of iceberg lettuce comfortably. I was hoping it would, so that I could replace another, longer, knife I had been using to make salads (the longer knife is harder to use on finer work, like cutting tomatoes, and it's a pain to use 2 knives). Not really the fault of the knife, but I found it difficult to find a 7 or 7.5" knife blade, which might be perfect for the salad cutting. I would also have preferred that the blade were not as tall, so that it would be a little more maneuverable in certain cutting situations (like cutting the top/core out of a tomato). So this knife has not fully satisfied the main reason I bought it. Anyway, still a good knife.

Great Product
I have used Spyderco kitchen knives for decades. I was very disappointed when they suspended production and I am delighted they are back on the market.

Very good kitchen performer
This K04SBK Spyderco knife is fabulous! I use it for slicing veggies as well as cold cuts and meat products. It also fillets very well. The serrated edge is so sharp, that it does not "crush" whatever you are slicing like most plain edge knives have a tendency to do. The product description did not mention it, but it is an excellent bread cutter.
