Jonard Tools FC-220 Fiber Cleaver- Precision Cleaving Tool for 250 µm & 900 µm Fibers, Carbide Blade (6,000 Cleaves), Accurate 2–20 mm Lengths, Single & Multi-Mode Compatible

All good

I terminate almost exclusively multimode fiber, so I can't speak for single mode. I generally get far better signal tests using this fiber cleaver over our corning pushbutton cleaver.

As long as you remove all cladding off fiber and keep blade clean, will work 100 percent of time.

Good tool. Easy to use, light and compact. This is a great tool for quick field mechanical splices.

Does not work well, fiber does not always cleave(cut) at the 'score' area. Sometimes the fiber will just break before or after the blade.

no good

not for precision but for short runs of MM fiber this will do the job.
