Overview & First Impressions
A hammered dulcimer hides its complexity: two bridges, dozens of courses, and a hundred strings whose tuning drifts the moment humidity moves. Setup work means cutting new strings cleanly, trimming winding ends flush at the tuning pins, and slicing felt and leather dampers to size. It is a bench of small, precise cuts, and the builder's blade earns its place through edge quality more than size.
Materials & Construction
Wound strings are the abrasive nightmare: the winding on a bass string polishes a soft edge round in a dozen cuts. CPM-S35VN's carbide structure shrugs it off, holding a keen apex through a full restringing session. The K9 K1151A3's camo carbon and titanium handle stands up to the metal dust and finger oil of a workshop bench, and Kansept knives' chamfering keeps it comfortable through long stringing nights.
Design & Details
The bolster liner lock gives the K9 a two-layer security feel: bolster and liner together backing the blade during pull-cuts against string tension. The CPM-S35VN blade's fine tip lifts a string end out of a pin field without scratching the soundboard, and the action stays smooth through the hundreds of open-close cycles a restringing day produces.
Real-World Use
Four cuts fill a setup session. Cutting new strings from the spool needs a clean slice so the wind never unravels. Trimming excess at the tuning pins needs a flush, confident pass that leaves no whistle-end. Slicing damper felt needs a fresh edge and a straight guide. Opening string packets and cutting padding needs a blade that will be wiped down anyway. One folder doing all four becomes the dulcimer builder's default tool.
Ownership Notes
Instrument builders compare working folders the way they compare tuners: with strong opinions formed by failure. Collectors of EDC knives already know the Kansept K9 family by its bolster liner lock and clean lines; the K1151A3 at EdcMall brings that hardware to a bench where a rolled edge means a frayed bass string and a lost evening. Builders who keep a rotation of folding knives in the shop agree that wound strings are the true test, because a bass winding polishes a soft edge round within a dozen cuts, and a frayed end at the tuning pin means trimming the whole string twice.
Who Is This For?
Buy it if you set up, string or build fretted and hammered instruments and want one blade that cuts wire winding without rolling. It suits dulcimer builders, harp technicians and guitar techs who string in volume. Skip it if your work is pure fretwire, since flush cutters own that. For the string-side cuts, steel this hard is not a luxury.
Final Verdict
The K9 K1151A3 is the dulcimer bench's quiet professional: CPM-S35VN edge retention through wound strings, a bolster liner lock that backs every pull-cut, and a handle that cleans of metal dust with a wipe. It looks like a collector's piece and works like a shop tool, which is exactly the right combination for a craft with a hundred strings and no patience for frayed ends.
