Method: https://bonsainest.com/how-we-research#our-score Wire that has done its job still has to come off, and the safest way is to cut it into short pieces rather than unwind it against the bark. Bonsai wire cutters have a rounded head so the jaws can sit flush against a branch without gouging it. They vary in jaw size, steel quality and the maximum gauge they will cut without damage. A cutter that stalls halfway through copper is a cutter that slips. We weighed cutting capacity against head size, since a large jaw handles thick wire but cannot reach into a crowded interior. Blade hardness, handle spring and long-term alignment counted too. Small heads suit shohin and dense ramification. Larger cutters suit growers using heavy copper on trunks and primary branches. Most people end up owning two, one fine and one stout, rather than compromising on either job. ## Picks ### 1.
