The King Cutter guarantees a royal start into the day. The absolute classic in the Boker program makes men's hearts skip a beat. The King Cutter has been a firm component of the Boker Straight Razor program since the start of the 20th century. With its practical 5/8" blade, it is the ideal knife for every morning, easy to use, and provides a very good shave even for inexperienced users. The non-stainless blade is made from best Solingen Straight Razor steel and easily handles everyday shaving. The blade is made by hand with an extra-hollow grind with belly. Inclusive authentic Boker stamp in blade. Delivered in historic packaging and certificate of authenticity.


The King Cutter Black with black synthetic handle is the best-selling Straight Razor of the Boker manufacture. The fine Boker tree inlay made from nickel silver is placed on the high-quality, moisture-resistant synthetic handle in painstaking manual work and then polished. The serration on both sides of the tang of the blue-polished blade provides an especially secure grip.

All of our razors come with a factory blade on them. They are ready to shave with after few passes on a strop. We recommend you strop your razor after you shave to help to maintain the blade's useful life between honing and keep the blade shave ready.

Nice Razor

Beautiful scales and ended up shaving well.

The factory sharpening could have been better. I had to put it on the hone much sooner than expected.

Excellent Boker Razor

Productions like a museum quality piece. Didn't even want to shave with it because I was concerned I would mess up how spectacular this blade looks. For just lining up my beard lines this 5/8" handles most excellent. Shaving with this razor is like a hot knife cutting through butter. Couldn't be more pleased. For anything other than lining up my facial hair I use a 6/8" blade or a 7/8" just because they seem to handle more facial hair in less time. I am sure it is all technique but each man will develop a certain preference or technique that works for them.
