What exactly is a Kuro-uchi knife?

Kuro-uchi literally means "black hammered." This technique of leaving the upper half of the blade unpolished after forging dates to way back in Japan and was a simple method of rust prevention. Look for a teal green or blue patina on the unpolished area on perfectly heat-treated Kuro-uchi blades.

The laminate style is called "Hon Warikomi" (literally "authentic wedging"), hence the "H" stamp on the blade, and means that the lamination is done by hand as compared to using available factory-laminated material.

A Kuro-uchi knife can be compared to a rustic piece of earthenware rather than a glazed piece of pottery.

They Keep Coming!

The latest batch of kitchen cutlery includes a number of Kuro-uchi knives, which you will find posted in its own category, the Kuro-uchi Series. Sizes range from a cute 3.7-sun Funayuki to a sleek 8.6-sun Sujihiki.

We will soon be posting the next group of kitchen knives, the Stainless Fukugozai Riveted Handle (SFGZ-RH) Series. Check this link often for some great pieces to round out your cutlery repertoire.

Another knife you may want to take a look at is a 12½" Outdoor Knife that Murray forged recently. It, too, is a Kuro-uchi and sports a unique hammered brass guard. This is one knife that will handle some heavy work for the outdoorsman.

The Three-Finger Test

The “three-finger test of edge sharpness” is a technique pioneered and popularized by Murray Carter. In our two sharpening DVD’s, the technique is demonstrated and explained in detail. Some feel, however, that this method is not as effective as claimed, that it is not possible to detect a burr or a wire edge using the technique. To set the record straight, let us fully explain to our readers the purpose and correct technique for employing the most expedient and valuable sharpness test there is -- the three-finger test of sharpness.

The foremost purpose in employing the three-finger test is to gain experience in discerning relative sharpness. We use our three fingers because:

1) they are more sensitive than the thumb;
2) it is ergonomically convenient (it feels natural);
3) unless you lose a finger or two, you will be able to use the same testing medium for the rest of your life.

We will gain experience over time by utilizing the best way to get direct feedback -- our fingers. The test is not dependent on any gadget or device enabling you to conduct it anywhere and any time you come across a blade. Again, to emphasize my point, we gain experience by doing it more often than any other test procedure.

By eventually testing hundreds of blades (and by starting with a new Carter Blade as a reference point), you will be able to easily discern not only relative sharpness, but also relative thinness in the edge as well as any defects in the edge such as micro chips, burrs or a wire edge. Additionally, there are some who fail to pick up on the equally important companion test to the three-finger test -- the Arm-Hair Shaving Test. If a blade shaves and feels scary sharp (with no edge imperfections) according to the three-finger test, then the blade is sharp. End of story. (N.B. Relative edge geometry of the primary and secondary edges is an important factor of strength but not of sharpness, and so, therefore, it is not discussed here.)

I can only conclude that if one fully understands what I have stated time and time again, has personally seen me demonstrate it to him, and has practiced the three-finger test to the point where his fingers can discern all the wonderful mysteries that can be easily discovered on a blade edge, then that person will fully appreciate my time-tested three-finger technique of testing blade sharpness.

Until our next email news,

Stay Sharp and may God richly bless you!
