Is #4F the longest size in the published range?

No. #4F is 9.5 mm (3/8 in); #3F is longer at 13 mm (1/2 in). Both are listed as Finish Cut, but the #3F breed and coat reference is not confirmed.

What does the 4FC reference mean?

4FC is the equivalent label for #4F at 9.5 mm (3/8 in) in the Jizu catalogue. Both use the Finish Cut designation.

Can the #4F coat examples establish a batch acceptance result?

No. The customer examples support selection discussion only. Agree a sample, test conditions and acceptance criteria for the actual order and request the corresponding inspection record.

#4F product and mounting demonstration

Shown: the carbon-steel moving-cutter configuration. Confirm the exact cutter configuration and clipper model before ordering.

15-second product-handling excerpt. The machine shown is demonstration equipment, not a universal compatibility claim. Video stills retain the original platform watermark. There is no spoken audio.

Review the teeth, markings and mounting connection shown here. Cutter material, branding and packaging are specified separately in your quotation and approved sample.

Review a longer retained-length requirement

The size sheet associates #4F with long-haired dogs. Customer context includes medium or curly coats and Poodle, Bichon Frise and curly-coated dog examples. A longer nominal length is not evidence that every coat can be clipped the same way.

Customer-provided selection reference

These catalogue references describe applications to review, not suitability for every dog of a named breed. A qualified groomer should assess coat and skin; veterinary preparation requires veterinary direction.

Coat context: Medium coat context, Curly coat context
Referenced breeds: Poodle, Bichon Frise, Curly-coated dogs
Referenced body areas: Full body, Face contour
Referenced use context: Standard-length grooming, Curly-coat grooming

Material choice is independent of the 9.5 mm listing. A steel fixed blade can be paired with a carbon-steel or ceramic moving cutter. Specify grade and coating in writing; neither is established by the F suffix.

Fixed blade material: Steel
Moving blade material options: Carbon steel, Ceramic
Steel grade options: 3Cr, 4Cr, 5Cr, 420J12, Custom

Compare nearby cut lengths

Compare nominal listed lengths, not a guarantee of the finished coat. Coat condition, preparation and handling affect the result.

For a buyer arranging a finish-length range, #4F sits between #5F at 6.3 mm (1/4 in) and #3F at 13 mm (1/2 in). Use the requested finish and prepared-coat sample evaluation to make the choice; do not infer #3F breed recommendations from the #4F sheet.

Blade specification	Listed cut length	Published use reference
#5F	6.3 mm (1/4 in)	Full body
#4F	9.5 mm (3/8 in)	Long-haired dogs
#3F	13 mm (1/2 in)	Longest finish cut

Confirm the clipper model before ordering

This is an A5 detachable blade, not a universal fit claim. Check the Compatible with model list, then include the exact model and a mounting photo in the RFQ. Blade size identifies cut length; it does not verify the machine.

Check Compatible with model references

Inspection evidence to request

For #4F, agree checks for the 9.5 mm (3/8 in) label, cutter alignment, tooth condition and nominated-clipper fit. Define a documented finish evaluation on the buyer's intended application instead of accepting a breed list as a batch performance report.

Jizu states an IQC / IPQC / OQC workflow. No size-specific hardness, tolerance, temperature, service-life or batch pass-rate results are published. The checks below are proposed purchase requirements, not measured results.
