My suggestion would be for the basic Tinker also - slim and light enough to carry easily, and provides a minimal set of tools. Then, there are several models that build on the Tinker tool set. The Super Tinker adds scissors, if you need them. The FieldMaster adds a saw, if you need that.
If you want to go simple, try the Alox-handled Pioneer series. Maybe the single layer, two blade model with large and small spearpoint blades.
They are all inexpensive and all well-made, so I suspect that this will not be your last. Have fun.
