Abstract
Abstract A knife and sheath in combination in which a two-headed bolt supported in the knife handle may be positioned to interlock with the sheath. The bolt is symmetrical with respect to the knife to permit insertion of the knife into the sheath in either direction. The sheath has a portion of a resilient flexible wall positioned to engage one head of the bolt to urge the other into a hole in the other side of the sheath to secure the knife within the sheath until the bolt is pushed firmly in the opposite direction to disengage the knife and the sheath.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A tool and sheath combination having releasably interlocking means comprising: said tool having a handle with a hole extending through said handle, a lock bolt positioned in said hole for axial movement thereof to and from a position in which one end of said lock bolt projects beyond a sidewall of said handle, and said sheath having opposite walls with one wall having a hole aligned with and normally receiving said one end of said lock bolt when said tool is fully inserted in siad sheath, and means on the other wall of said sheath for engaging and normally urging the other end of said lock bolt to siad position comprising a resilient flexible wall section having leaf spring-like function whereby said one end of said lock bolt engages said hole in said one wall.
Claim 2
Dependent Claim
135 words
A tool and sheath combination having releasably interlocking means comprising: said tool having a handle with a hole extending through said handle, a lock bolt positioned in said hole for axial movement thereof to and from a position in which one end of said lock bolt projects beyond a sidewall of said handle, and said sheath having opposite walls with one wall having a hole aligned with and normally receiving said one end of said lock bolt when said tool is fully inserted in siad sheath, and means on the other wall of said sheath for engaging and normally urging the other end of said lock bolt to siad position comprising a resilient flexible wall section having leaf spring-like function whereby said one end of said lock bolt engages said hole in said one wall.
Claim 3
Dependent Claim
44 words
A tool and sheath as set forth in claim 1 wherein said bolt is formed with a center shaft and enlarged heads at either end, said hole in said one wall of said sheath having a diameter sufficient to receive and engage said heads.
Claim 4
Dependent Claim
15 words
A tool and sheath as set forth in claim 2 wherein said sheath is symmetrical.
Claim 5
Dependent Claim
168 words
In a knife and sheath combination, means for removably securing the knife in the sheath comprising: said knife having a hole through the handle, means permanently securing a bolt in said hole for reciprocal axial movement, said bolt having an axial length greater than the thickness of said handle at said hole, means formed at least in part by said handle for permitting said bolt to be moved axially to and from positions in which the bolt selectively projects beyond either, but not both, sidewalls of said handle at one time, said sheath having lower walls to receive the knife blade and upper walls facing the sidewalls of said knife handle, one of said upper walls having a hole aligned with and adapted to receive one end of said bolt when the knife is fully inserted, and the other of said upper walls functioning as a leaf spring in engagement with the other end of said bolt for normally, biasing said bolt to one of said selective positions.
