## Abstract

Vegetation stem cutting apparatus comprises (a) elongated tongs which are interconnected at a pivot, (b) a table carried by one tong proximate the end thereof, (c) and a knife carried by the other tong to close toward the table when the tongs are pivoted to cut the stem placed on the table, (d) the knife extending at a substantial angle relative to a normal to the table when the knife edge is closed into proximity to the table.

## Claims

### Claim 1

Vegetation stem cutting apparatus comprising
(a) elongated tongs which are interconnected at a pivot,
(b) a table carried by one tong proximate the end thereof,
(c) and a thin knife carried by the other tong to close toward the table when the tongs are pivoted to cut the stem placed on the table,
(d) the knife extending at a substantial angle relative to a normal to the table when the knife edge is closed into proximity to the table,
(e) the thin knife defining a first plane, and the table surface defines a second plane, said planes intersecting non-perpendicularly when the knife edge is closed into proximity to the table, the direction of relative closing of the thin knife toward the table surface being angularity offset at an angle .beta. from a perpendicular to said surface,
(f) and a shallow groove in said surface to receive only an edge portion defined by the blade.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein the knife defines a first plane, and the table surface defines a second plane, said planes intersecting non-perpendicularly when the knife edge is closed into proximity to the table.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein the table has a non-metallic surface facing the knife, to be engaged by the knife.

### Claim 4 (depends on 3)

The apparatus of claim 3 wherein said surface consists of wood.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein said table has a surface facing the knife, the material of said surface being softer than the material of the knife.

### Claim 6 (depends on 2)

The apparatus of claim 2 wherein said second plane extends in the general direction of said one tong.

### Claim 7 (depends on 6)

The apparatus of claim 6 wherein said table has a linear locus of engagement by the knife edge, said locus extending in the general direction of said one tong, that locus also acting as an indicia for flower placement adjacent the table, said locus defined by said shallow groove which extends into the table at said angle .beta. which is between 20.degree. and 40.degree..

### Claim 8 (depends on 1)

The apparatus of claim 1 including a spring connected to the tongs to urge them in directions tending to separate the knife and table.
