Abstract
Abstract An implement handle is made for use by a crippled person, utilizing a cap adapted to receive an end of the implement and an initially flexible bag attached to the cap. Material in the plastic state is inserted into the bag, the material becoming rigid with the passage of time, and the bag is placed into the hand of the crippled person while the material is becoming rigid. The crippled person maintain a substantially constant grip on the bag during this process, whereupon the rigidified handle conforms itself to his particular grip.

Claim 1
Independent Claim
111 words
A method of making, for use by a crippled person, a handle for an implement having an engagement end, the method comprising the steps: (a) providing a cap adapted to receive the said engagement end, and an initially flexible bag attached to the cap, (b) inserting into the bag a material in the non-rigid state which becomes rigid with the passage of time, the material and the bag being of materials that will adhere together when the material becomes rigid, (c) placing the bag in the hand of the crippled person, and (d) having the crippled person maintain a substantially constant grip on the bag while the said material becomes rigid.
Claim 2
Independent Claim
