My set grew legs a few years ago :O( Treat the sheath with a good beeswax dressing and the birch with tung oil. These blades have very subtle handling advantages. Reverse grip the little puukko with the blade pointed down and edge facing you. Your thumb will find a natural purchase on hte butcap. This makes for controlled scribework, such as grooving wood for arrow fletches, gaff hooks etc. The Lueko is best handled with draw cuts, or pushing into material from the buttcap again. These are superb blades to use with mittens.
