Each handle has an outwardly curving handle core surrounded by a silicone gel filled retention tube encompassed by a cover tube comprising silicone rubber having a thickness of between about 3 and about 7 mm, the end of each pliable cover tube spaced from the journal being closed. The open ends of the pliable cover tube and the retention tube are sealed by an annular collar extending round the handle core. A flexible, inwardly curving leaf spring, retained by each collar, urges the jaws out of engagement when the handles are urged together. ## Claims ### Claim 1 Beading pliers comprising: a pair of engageable jaws pivotable about a journal, each jaw being integrally connected to an outwardly curving handle core, each said handle core having a semicircular cross section with a flat portion, wherein the flat portion of the semi-circles face each other, wherein each said handle core terminating at a handle core end spaced from said journal; a retention tube surrounding each said handle core, each said retention tube being closed around the handle core end, following a curve of the handle core, and being open at an end proximate said journal; an open ended pliable cover tube comprising silicone rubber encompassing each said retention tube, the open end of each said pliable cover tube being adjacent the open end of said retention tube, the end of each said pliable cover tube spaced from said journal being closed; an annular collar extending around said handle core and the open ends of said pliable cover tube and said retention tube, wherein the annular collar seals the open ends of said pliable cover tube and said retention tube; viscous silicone gel being disposed in the space between each said retention tube and each said pliable cover tube; and a flexible inwardly curving leaf spring being retained against each said handle core by each said annular collar, said flexible inwardly curving leaf spring urging said jaws out of engagement when said handles are urged together; wherein each said annular collar is operative to retain the respective pliable cover tube and the respective retention tube on the respective handle core; wherein the open end of each retention tube terminates within the respective annular collar adjacent to the respective flexible inwardly curving leaf spring; and wherein each handle core has a diameter between about 3/16 inch and about 7/16 inch, the open-ended pliable cover tube on each handle core has a thickness of about 3 mm to about 7 mm, and the open-ended pliable cover tube on each handle core has a width of at least 12.5 mm. ### Claim 2 (depends on 1) The beading pliers of claim 1, wherein said viscous silicone gel substantially fills the space between said retention tube and said cover tube. ### Claim 3 (depends on 2) The beading pliers of claim 2, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.25 and about 6.5 mm. ### Claim 4 (depends on 2) The beading pliers of claim 2, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.5 and about 6 mm. ### Claim 5 (depends on 2) The beading pliers of claim 2, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.75 and about 5.5 mm. ### Claim 6 (depends on 1) The beading pliers of claim 1, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.25 and about 6.5 mm. ### Claim 7 (depends on 1) The beading pliers of claim 1, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.5 and about 6 mm. ### Claim 8 (depends on 1) The beading pliers of claim 1, wherein each open ended pliable cover tube comprises silicone rubber having a thickness of between about 3.75 and about 5.5 mm. ### Claim 9 (depends on 8) The beading pliers of claim 8, wherein the cross-section of each said handle core has a diameter between about 7/32 and 13/32 inch. ### Claim 10 (depends on 8) The beading pliers of claim 8, wherein the cross-section of each said handle core has a diameter between about 15/64 and 25/64 inch. ### Claim 11 (depends on 8) The beading pliers of claim 8, wherein the width of the cover tube on each handle is at least 13 mm. ### Claim 12 (depends on 8) The beading pliers of claim 8, wherein the width of the cover tube on each handle is at least 14 mm. ### Claim 13 (depends on 8) The beading pliers of claim 8, wherein the width of the cover tube on each handle is between 15 and 20 mm. ### Claim 14 (depends on 1) The beading pliers of claim 1, wherein the cross-section of each said handle core has a diameter between about 7/32 and 13/32 inch. ### Claim 15 (depends on 1) The beading pliers of claim 1, wherein the cross-section of each said handle core has a diameter between about 15/64 and 25/64 inch. ### Claim 16 (depends on 1) The beading pliers of claim 1, wherein the width of the cover tube on each handle is at least 13 mm and said viscous silicone gel substantially fills the space between said retention tube and said cover tube. ### Claim 17 (depends on 1) The beading pliers of claim 1, wherein the width of the cover tube on each handle is at least 14 mm and said viscous silicone gel substantially fills the space between said retention tube and said cover tube. ### Claim 18 (depends on 1) The beading pliers of claim 1, wherein the width of the cover tube on each handle is between 15 and 20 mm and said viscous silicone gel substantially fills the space between said retention tube and said cover tube. ### Claim 19 (depends on 1) The beading pliers of claim 1, wherein the closed end of the retention tube is spaced from said journal;
