Constructed of heavy-gauge aluminum that results in strong joints and excellent tactile transmission. They are easy to fold and have an extra knot that allows for easy replacement with any hook-style Ambutech tips. The PAS4020's come with a marshmallow non-rolling tip and a ribbed putter handle. Canes are available in 2" increments from 36" to 60" in 4, 5 or 6 sections, depending on the size. When ordering, indicate both the cane length and preferred sections.
