In my view, the danger of getting a lower-quality "starter" scythe is it will not be as effective as you would like and that 1) you develop bad habits that lead to fatigue and/or injury and 2) you give up on the scythe because it seems ineffective, inefficient, etc.
Snaths such as these that are not adjustable (one size "fits" many) are not ideal in that it will kinda-sorta fit you but not totally fit you, thus making mowing less effective and making you put more effort into mowing. Furthermore, the left grip looks like it might easily slip sooner or later (grip slippage is all but impossible with different snath designs). And I am not a fan of aluminum snaths. They won't crack or break like a wooden snath, but they'll bend, rendering them useless. I also don't like their feel as you move the blade through the grass.
I also can't tell who the manufacturer of the blade is nor can I figure out anything about the whetstone (
course? fine? natural? artificial?). Anyone have insight on this?
On the other hand, splurging for a relatively-expensive kickass scythe right from the get-go, before you know for sure that this is the tool for you, might not be realistic for you, so you'll have to balance that, of course. Seeking out a mowing
class, where high-end scythes are available for use, might help give you a better idea--better idea than a "starter" scythe, that is--as to whether you truly want to use a scythe for your land-management needs.
