Pro:
as described good hand guide
non-slip grip with sound professional
quick change of the blade
separate threads of yarn etc possible thank notch (see picture)
Cons:
there was not any protective cover or the like, and from my old Dolphin knife that fit
has been able to use only straight blades
Conclusion - even my colleagues thought the knife was top - despite and perhaps because of the weight it fits comfortably in your hand and can perform clean - and can handle well the small as well as large hands so.
Unfortunately mine is now broken gegang - right at work I could not switch the blade - maybe you should also fast changing method waive especially if it is plastic
but I'll get myself a later
