セラミックFOREVER ceramic knives are made in Japan from high purity zirconium oxide powder. The powder is pressed in a blade shaped mold then sintered (fired) at high temperature to produce extremely hard, high density,
non-porous ceramic which is far superior to that of our competitors. We have been making ceramic knives since the 1990s and, because we were originally a manufacturer of powder compaction presses, we manufacture the press machinery that we use to make our knives.

FOREVER ceramic is harder than other ceramic knives and it is this hardness that enables it to stay sharp over a longer period than ANY other ceramic knife. Independent test results (see below) show that a FOREVER ceramic knife can cut 56m of test paper before becoming blunt, several times superior to our competitors.

High Density = High Cutting Edge Retention

Q. Why do Forever ceramic knives outperform other ceramic knives in cutting edge retention testing? Aren’t all ceramic knives the same?
A. Not all ceramic knives are the same. There are many differences in raw materials and manufacturing methods and that leads to finished products of greatly differing quality, as can be seen in cutting edge retention test results. Forever’s high density ceramic knives are 100% manufactured in Japan using Japanese raw materials and our own unique manufacturing method.

Independently Verified Superior Cutting Edge Retention !
On average 9.2 Times Superior Cutting Edge Retention to Competitor Ceramic Knives !
On average 280 Times Superior Cutting Edge Retention to Stainless Steel Knives !

Color Ceramic Knives

カラーセラミック
Forever’s series of color ceramic knives come in three colors: pink, yellow and green. Only Forever has the technology to produce such original ceramic knives. Add color to your kitchen with our color series.
カラーセラミック
The color is not a coating nor is it painted on to the blade so it will never fade over the lifetime of the knife.

FOREVER ceramic scissors are available in 3 blade sizes – 50mm, 60mm and 80mm – and in both white and black blades. Ceramic scissors are lightweight, handy, easy to clean and will never rust. These scissors are suitable as kitchen/household scissors and for use in more specialist applications.

Kitchen/household scissors

Can be used to cut lettuce, herbs and meat. Ceramic is a chemically inert material – it will not cause food to turn brown or leave a metal smell, maintaining the appearance and natural odor of food. Also suitable for cutting food wrapping and other plastic packaging or as general household scissors.

Kevlar and other fabrics

Kevlar fabrics and other fibers soon cause steel scissors to become blunt but FOREVER ceramic scissors can cut such materials while still retaining their sharpness over a long period. Since ceramic is non-magnetic, these scissors can be used to cut magnetic media without causing damage or contamination.

Comparative cutting edge retention test of scissors

We tested the cutting edge retention of 3 pairs of scissors by cutting abrasive sandpaper and stopped the
test when the scissors became blunt. The amount of sandpaper cut is an indication of the cutting edge retention
ability of the scissors.
世界初折るセラミックカッター
FOREVER is the world’s only manufacturer of ceramic snap off blades. We used the know-how we developed as
a press manufacturer to make these ceramic blades with multiple segments that can be snapped off when necessary. FOREVER ceramic blades possess several features that steel blades do not and as a result they can be used for many different applications.
WEAR RESISTANCE: Ceramic stays sharp over a long period.
RUST RESISTANCE: Ceramic is not a metal so it will never rust, making it suitable for cutting tasks that involve moisture or water.
NON-MAGNETIC: Ceramic is non-magnetic so it can be used when working with strong magnetic materials or for cutting media would otherwise be damaged by steel blades.
NON-CONDUCTIVE: Ceramic will not conduct electricity. It can be used to cut electrical wiring and has been used in EOD missions for many years.
CHEMICAL RESISTANCE: Ceramic is impervious to acids and alkalines. It can be used in applications involving chemicals and it will not affect the blade.

OLCERA Cutting Edge Retention Data

刃のなが切れ実験データ
FOREVER ceramic snap-off blades are many times harder than steel snap off blades. It is this hardness that enables them to stay sharp over a much longer period than steel knives. Wear resistance testing conducted at CATRA in the UK showed that a FOREVER ceramic blade became blunt after cutting 25,490mm of abrasive test paper. To put that amount into perspective, a brand name steel blade could only cut 426mm of test paper before it became blunt.
