1) Alaska Pik'sTM plastic and brass picks can be manicured to precise length: (Plastic) use clippers, then file. (Brass) use file or grinder. To manicure, place pick securely "Over the Finger, Under the Nail,TM" decide the length desired, then clip and file. For a side of the fingernail attack remove plastic at indicator #1.
2) To match the curvature of the user's flesh under the nail area, file on the backside of the picking surface (indicator #2). This adds security. This should be done before changing the length.
3) To un-stiffen the pik, remove all or part of the pressure band (indicator #3). For added comfort, file smooth all uncomfortable edges. The brass pressure band should be bent inward. This creates tension on top of the fingernail (indicator #3).
