The Missing UH’s
In 1980 Schrade produced a new knife which they initially named the I.V.L.B. which in
fact was the LB4. The knife was produced until 1985 with a total of 5107 knives being
In 1983 Schrade introduced a pattern line called the “3Rd Generation” consisting of 7
knives one of which was the C641 built on the same frame as the I.V.L.B. I cannot find
any I.V.L.B. having been built that year.
In 1984 Schrade made 2 new UH knives, the 707UH and the 892UH, in very low
numbers. These were produced for only 2 years each being built on an existing 3rd
Generation frame. The 707UH was later released in 1991 in a completely different
configuration with a single blade and a small scissor.
The 707UH totaled 1724 shipped and the 892UH totaled 1673
3Rd Generation C641

Information gathered from multiple sources including the notes from Herman Williams, Robert Clemente,
Debbie Chase. Pictures of the 707UH and 892UH were supplied by Dave Kaplan. The LB4, newer 707UH
and 3Rd Generation pictures are from my collection.
