I've used these: http://midwestvineyardsupply.com/Pr...catid=87&cat=GrapeFork<sup>tm<sup>&Type=False
they work great, just garb the bunch and shove the Grapefork at the stem and it drops in your hand, no cramping from pruners and clippers. Also you can't get cut like with a knife. Blades are replaceable too.
