A first handle has a receiving slot disposed and centered lengthwise on the interior surface. A second handle has a receiving slot disposed and centered lengthwise on its interior surface. The tool has two legs that are parallel, and have a thumb stud on one leg. First and second handles are attached to opposing sides of the tang. The tool is inserted into the knife by the legs entering the first and second receiving slots while straddling the tang. ## Claims ### Claim 1 A knife having a blade at a distal end and a knife base at an opposite end, comprising: a tang having a thickness and an end recess having a depth at the knife base; a first handle having a first handle recess and a first handle interior surface having a first handle receiving slot disposed lengthwise approximately centered on the first handle interior surface; a second handle having a second handle interior surface having a second handle receiving slot disposed lengthwise approximately centered on the second handle interior surface; a spacer having a spacer thickness slightly greater than the thickness of the tang and a spacer length approximate the depth of the end recess; a tool having a first leg having a first leg end and a second leg having a second leg end, the first leg and the second leg are essentially parallel and attached to either side of the spacer at the first leg end and the second leg end; and, a thumb stud disposed on the first leg approximate the first leg end on a side opposite the spacer; wherein, the first handle interior surface is attached to the tang on a first tang side and the second handle interior surface is attached to the tang on a second tang side, the tool is inserted into the knife at the knife base by the first leg and the second leg entering the first handle receiving slot and the second handle receiving slot, respectively, while straddling the tang and the spacer is lodged into the end recess of the tang while the thumb stud lodges into the first handle recess such that the thumb stud protrudes slightly from the first handle such that a user contacts the thumb stud to slide the tool into and out of the knife. ### Claim 2 (depends on 1) The knife of claim 1, further comprising: a deflection slot disposed interior to and approximately centered on the tang; at least two serrated ridges disposed across an outer surface of the first leg; and a detent pin attached to and disposed through the first handle, the detent pin having a end extending toward the tang; wherein, as the tool is inserted into the knife base the end of the detent pin presses against the serrated ridges deflecting the first leg into the deflection slot and holding the tool firmly in place by the detent pin lodging between two of the serrated ridges. ### Claim 3 (depends on 2) The knife of claim 2, wherein the detent pin is a removable ball screw. ### Claim 4 (depends on 2) The knife of claim 2, wherein the detent pin is stainless steel. ### Claim 5 (depends on 2) The knife of claim 2, wherein the detent pin is ceramic. ### Claim 6 A knife having a blade at a distal end and a knife base at an opposite end, comprising: a tang having a thickness and an end recess having a recess size approximate that of the end recess of the tang having a depth at the knife base; a first handle having a first handle recess and a first handle interior surface having a first handle receiving slot disposed lengthwise approximately centered on the first handle interior surface; a second handle having a second handle interior surface having a second handle receiving slot disposed lengthwise approximately centered on the second handle interior surface; a tool having a first leg having a first leg end and a second leg having a second leg end, the first leg and the second leg are parallel and spaced apart slightly greater than the thickness of the tang; and, a thumb stud disposed on the first leg opposite the first leg end exterior to the tool; wherein, the first handle interior surface is attached to the tang on a first tang side and the second handle interior surface is attached to the tang on a second tang side opposite the first tang side, the tool is inserted into the knife at the knife base by the first leg end and the second leg end entering the first handle receiving slot and the second handle receiving slot, respectively, while straddling the tang, the tool is lodged into the end recess of the tang while the thumb stud lodges into the first handle recess such that the thumb stud protrudes slightly from the first handle such that a user contacts the thumb stud with a user's thumb to slide the tool into and out of the knife. ### Claim 7 (depends on 6) The knife of claim 6, further comprising: a first liner having a first liner receiving slot disposed between the first handle and the tang such that the first liner receiving slot aligns with the first receiving slot of the first handle; and a second liner having a second liner receiving slot disposed between the second handle and the tang on a side opposite the first liner such that the second liner receiving slot aligns with the second receiving slot of the second handle; wherein, the first leg end enters first receiving slot and first liner receiving slot simultaneously and the second leg end enters second receiving slot and second liner receiving slot simultaneously, thereby lodging the tool into the knife base of the knife. ### Claim 8 (depends on 6) The knife of claim 6 is a pocket knife. ### Claim 9 (depends on 6) The knife of claim 6, further comprising: at least two serrated ridges disposed across an outer surface of the first leg; and a detent pin attached to and disposed through the first handle and the first liner, the detent pin having a end extending toward the tang; wherein, as the tool is inserted into the knife base, the end of the detent pin presses against the serrated ridges deflecting the first leg into the first liner and an outward spring force biases the first leg outward holding the tool firmly in place by the detent pin lodging between two of the serrated ridges. ### Claim 10 (depends on 2) The knife of claim 2, wherein the detent pin is a removable ball screw. ### Claim 11 (depends on 2) The knife of claim 2, wherein the detent pin is stainless steel. ### Claim 12 (depends on 2) The knife of claim 2, wherein the detent pin is ceramic. ### Claim 13 (depends on 7) The knife of claim 7, wherein the tang is an alternate tang. ### Claim 14 (depends on 13) The knife of claim 13 is a folding knife. ### Claim 15 (depends on 6) The knife of claim 6, further comprising: a spacer having a spacer thickness slightly greater than the thickness of the tang and a spacer length approximate the depth of the end recess, wherein the first leg end and the second leg end are attached to either side of the spacer. ### Claim 16 (depends on 6) The knife of claim 6, further comprising: a sleeve aperture disposed in the first leg; a thumb sleeve disposed in and fixedly attached in the sleeve aperture; a spacer rivet has an alternate spacer having the thumb stud extending from a spacer top and a rivet base extending from a spacer bottom; a rivet aperture is disposed in the second leg; wherein, the rivet base is disposed in the rivet aperture and fixedly attached to the second leg, the thumb stud extends through the thumb sleeve such that the thumb stud rotates within the thumb sleeve thereby allowing the tool to rotate between a closed position and an extended position. ### Claim 17 (depends on 16) The knife of claim 16, further comprises, a screw driver on the first leg end. ### Claim 18 (depends on 16) The knife of claim 16, further comprises, a hex hole disposed in the first leg. ### Claim 19 (depends on 16) The knife of claim 16, further comprises, a hex wrench disposed in the second leg end. ### Claim 20 (depends on 16) The knife of claim 16, further comprises, an abrasive coating on the first leg.
