While your FELCO Pruners may last a lifetime, even the high-quality stainless steel FELCO uses to produce its blades can wear down over time through repeated sharpening and extensive use. If the pruner's anvil blade is worn or nicked, cracked or misaligned from use, a FELCO Pruner Replacement Anvil Blade for the F-100 Pruner will make a world of difference. Replace the anvil blade, and restore your FELCO Pruners to their original peak performance.
