There are anvil-type pruners, and there are scissor-type pruners. And now, gardeners can buy double-edged pruners. The Taia clipper, commonly used by professional vineyardists, is newly available for home gardeners. Imported from Italy, it features two sharp blades that make a clean cut. The Taia comes in two designs for different purposes: One style has pointed blades for reaching thorny branches such as roses, and the other has rounded blades with a flat side for extremely close and precise cuts, as in bonsai. The two tempered-steel blades can be sharpened easily and adjusted with screws located under its spring to tighten blades even if they wear.
The Taia is somewhat heavier than other pruners I've used, but it's better than ordinary pruners for tasks such as grafting, creating hardwood cuttings, slitting stems in half or quarters, or pruning bonsai. Taia is available from the Rare Fruit Council International, 14735 SW 48 Terrace, Miami, Florida, 33185, or call (305) 554-1333. The pruner sells for $50, which includes shipping and handling.
