Scythe Starter Kit
This is a great way to get started with scythe mowing. Includes everything you need: a snath, blade, peening jig, field whetstone and holder, and an invaluable book explaining use and maintenance.
The metal snath is good for people between 5 and 6 feet tall, while folks over 6 feet may prefer the wooden snath OR choose to slightly bend the metal snath to correct the angle of the blade.
As for blade length, longer lengths will be more productive mowing delicate or shorter vegetation (such as a hay field), while shorter blades may be easier to work in tougher material (like goldenrod, for example).
The "stone tip" blades reinforce and protect the leading edge of the blade from errant rocks, which many users appreciate. It does take away from the usable edge of the blade slightly.
Falci blades are made in Italy. SHW blades are made in Germany.
