Hi,
I dont know,
Seems like a mystery,
.060in = 1.524 mm
.125in = 3.175 mm
and " tsprof.com constructor " says
K02 Single Clamp 5mm minimum
K02 Double Clamp b5mm minimum
K02 Fillet Clamp 2.5mm maximum
K02 Single Clamp
Swivel symmetrical clip for double-sided grinding without reinstalling of knife. Clamp structure allows to clamp rigidly and symmetricaly knives with complex blade geometry. It is perfectly suitable for hunting and folding with wide spine. Narrow spine knives are not recommended to be sharpen using single clamp as it can be bent.
Recommended knife lendth for the clamp: 50-200 mm.
Minimal knife width 20 mm, spine thickness 5 mm, angle range 10-32 degrees (wide knife range can be different).
Clamp sponges are made from aglow sprung-spring steel 65 g. It isn't suitable for K-01 model. Sponges, screws and flat springs can be bought separately.
K02 Single Clamp
Swivel symmetrical clip for double-sided grinding without reinstalling of knife. Clamp structure allows to clamp symmetricaly and rigidly knives with complex blade geometry. It has an independent mechanism of reinstall clamping sponges. It's suitable for cutlery and fillet knives with narrow spine. In contrast to single clamp, thin knives can be pinched in double clamp only. Thanks to two clamp points thing knives are pinched more rigidly and they are not bent being in double clamp. But in contrast to single clamp double clamp has more narrow sponge of 16 mm in width therefore knives with spine more that 3.5 mm in width are not recommended to be pinched. Minimal distance between the sponges is 40mm., maximal 130 mm.
Recommended knife length for the clamp is 30-300 mm.
Minimal knife width 20mm, thickness in spine 3.5 mm, range of angles 10-32 degrees (range can be changed for wide knives). Clamp sponges are made from aglow sprung-spring steel 65 g.Suitable for K-01 model. Sponges, screws and flat springs can be bought separately.
K02 Fillet Clamp
Special pliers for narrow netting knives with reduced grinding angle. The thin jaws of the clamp are made from spring steel which provides sufficient clamping force. The clamp with the modified configuration of the jaws and the application of the special screws have minimum final sharpening angles of 6.5 g. for each side. It is not recommended to use knives with a thickness of more than 2.5 mm. to avoid damage to sponges.
Recommended knife length for pliers: 30-300 mm. The minimum width of the knife is 10 mm, the thickness of the spine is 2.5 mm, the range of angles is 6.5 to 32 degrees (the range wide knife may be different).
Suitable for K-01. Sponges, screws and flat springs can be purchased separately.
