A hose cutter sized to handle everything from AN3 up to AN20, which covers the entire range of braided hose most workshops will ever assemble. Cutting braided hose properly is the difference between a hose end that assembles first time and one that fights you: a hacksaw or angle grinder frays the stainless braid, leaves the cut off square and makes it almost impossible to feed the hose into the socket without pushing strands into the fitting. This tool shears the hose cleanly and squarely instead. If you build more than the occasional hose, it pays for itself quickly in saved fittings and saved frustration, and it belongs in any shop assembling AN plumbing regularly.
