[0008] A tool comprising a middle part or handle having a curved claw at one end and a notched pry or nail extractor at its opposite end, and having a transverse cylinder between said handle and said pry, the ends of which serve as hammer faces and the projecting sides as fulcrums for the pry and the nail extractor.

[0009] A hand tool employs a generally spherical handle with a housing and a drive member seated therewithin for engagement of a tool member for positive drive action in one direction. One-way clutch means within the housing permits relative rotation of the drive member in a first direction and interengagement for joint movement in the direction opposite thereto.

[0010] A tool assembly for mounting bits includes a tubular shank with an enlarged end portion in which is seated a tool bit receiving socket and its other end inserted into a handle. The socket has a cavity opening at the outer end in which is seated the body portion of tool bits. Releasable retaining means in the cavity retains the inserted tool bits which seat against a shoulder therewithin. The socket itself has a peripheral collar seated against the end of the shank and seats internally against a shoulder within the cavity of the shank provided by the enlarged end portion.

[0011] A screwdriver including a relatively large teardrop-shaped, hollow handle, comfortable to the hand for delivering increased turning power, is provided with a self-contained ratchet mechanism which, in turn, has a three-position ratchet control (forward, reverse and lock). The shank of the screwdriver houses a magnet for releasably holding any one of a number of bits in place during use. The handle has a series of finger-engageable projections on its stem to assist the operator in applying torque and for storage of bits therein. A retainer ring on the stem holds the bits in the chambers until indexed to a bit-releasing position.

[0012] The box top opener is of one piece molded plastics material and includes an elongated reinforced handle portion having reinforced box top gripping jaws extending from one end thereof. The jaws are comprised of a pair of flat parallel closely spaced apart plates adapted to receive the box top therebetween. The upper jaw has a rectangular configuration and the lower jaw has a triangular configuration with the edges thereof beveled to facilitate insertion under the box top whereby upon lifting of the handle the portion of the box top engaged between the jaws will be separated from the sides of the box and lifted upwardly to provide access to the contents of the box.

[0013] A combination tool comprising a ball-shaped handle member and at least three substantially straight work-engaging members projecting substantially radially from said ball-shaped handle member, the tips of said work-engaging members defining a plane spaced from the surface of said handle member. At least three orientation rings are provided, each extending along the intersection of the surface of the handle member with a plane extending through the handle member center at right angles to one of the work-engaging members.

[0014] Apparatus for removing a musket ball undesirably lodged in the breech of a muzzle-loading gun. The apparatus includes a ramrod to one end of which a ball starter is secured firmly but manually removable and to the opposite end of which a screw-jag tool is similarly secured. Using the grip of the ball starter as a handle, the tool is screwed into the musket ball and is then withdrawn through the barrel. To prevent rotation of the grip of the ball starter relative to its shaft when the musket ball is being engaged and disengagement of the ball of the ball starter when the musket ball is being pulled out, the shaft of the ball starter is keyed to its grip. Normally the ramrod is carried on the gun and the ball starter and screw-jag tool are carried in the pouch with the bullets and powder.

[0015] A driver tool utilizing a sleeve which fits within and rotates with an elongated shaft. Driving bits are held to the sleeve and turned by the action of the rotating shaft. A handle which is expandable connects to the elongated shaft.

[0016] Scissors have a pair of pivotally interconnections blades and a ball-shaped handle. One embodiment has a pair transversely spaced, outwardly-convex, partly ball-shaped handle members at the rear end portions of the blades and an elastomeric member compressibly interposed between the handle members biasing the blades toward an open position. The handle members and elastomeric member have complementary, partly ball shapes providing an overall external configuration of a single ball. Another embodiment has a hollow, flexible ball completely covering and enclosing partially ball shaped handle members, the pivotal interconnections between the blades is concealed within the ball shaped covering, and a formed wire spring member is anchored at the interconnections and its opposite ends are seated against inner surfaces of the handle members. In each embodiment, manual squeezing pressure applied by a user's palm or fingers closes the blades against the bias of the elastomeric or wire spring member.

[0017] A holder for carrying a ball starter on the barrel on a muzzle loading and/or black powder rifle. The holder, secured to the rifle barrel, presents ready access to the ball starter and precludes any previously encountered inconvenience in locating the ball starter on the person of the user or in the general vicinity of use. The holder is conveniently mounted and provision is made for the selective retention of the ball starter thereon, i.e. from release from a stored position to positive placement at such storage position.

[0018] A package opener that can be used safely to open packages, such as jewel boxes containing compact discs, that are encapsulated within thin outer coverings. The device includes an edge guide channel into which a cutting edge extends so that the device can be guided along a selected edge of the package to precisely cut the covering to permit its easy removal from the package.

[0019] A palm driver has a rotatable drive member and an ergonomic handle body connected to the drive member through a ratchet mechanism and covered by a cushioning grip. The handle body is asymmetrically curved and is substantially continuously convex along portions engageable in use with the user's hand, having a generally flattened top surface opposite the drive member and receivable in the user's palm, and a peripheral side surface which has a plan outline which is continuously convex and has a generally flattened heel portion and an opposed, much smaller radius finger portion, respectively engageable with the heel and fingers of the user's hand in use.
