I would appreciate feedback (comments) concerning the designs I have created for these ceramic pocket knives. Obviously a niche market but I feel that the ceramic blades are particularly suited for small ceramic pocket knife application. The folding action protects the black ceramic blades from damage and these two sizes of ceramic pocket knives do, in my mind, cover the majority of requirements. The ability to retain sharpness means the ceramic pocket knife will be ready to cut whenever required! YES, you can improve the edge and maintain it using a 600 grit diamond hone and ultra fine silicone carbide wet/dry sanding paper. Please read the SHARPENING page.
Black Ceramic Pocket Knife Blade or White Blade? OK, there some increased hardness in a black ceramic knife blade but in reality the white blade is already so hard that this increase makes very little difference in terms of the ability to retain an edge. The only real reason, in my opinion, to purchase a black ceramic folding pocket knife is one of appearance. It just feels strange using a knife with a white blade that you can almost see through. The black blade on a ceramic pocket knife gives a much more traditional appearance & darn it, just plain looks better! The black blades are however, more expensive to produce, as they have to go through a secondary Hot Isostatic Process where pressure and extremely high temperatures physically change the blade from white to black and increase density & hardness. Keep in mind that increased hardness does also increase brittleness so a white ceramic bladed knife might actually be tougher in some applications as it would be more resistant to chipping.
Ceramic knives and cutting blades have proven very useful within the EOD Community and a large percentage of my sales are to meet Military and Police requirements. Ceramic blades also have some very specific industrial uses and although customers do not often inform me of their applications, I do know that trimming aerospace composite molded parts does require a ceramic blade. Cutting Kevlar or other very tough fabrics/ropes such as spectra lines is also a common application for these blades.
Engraving with a laser has been done for some special orders but setup and extra work requires a minimum of 25 knives. Contact me if this service would be useful to your business. Before you ask, no engraving is possible on the knife handles.
