I used to have a TYZAK Sheffield Steel bladed scythe , with a 1 & 3/4 " double handled aluminium shaft .
It was fantastic , light ,well designed , you can fit it to yourself with ease & with a fine rub stone I could get it razor sharp .
There is one on eBay at the minute . Item number 142042348516
I paid about £40 for mine 20 years or more ago , so that one is fair priced even with the carriage costs .
The old hand mower mens way of knowing your scythe was sharp enough was , first use a coarse carborundum stone to start the edge and then use a fine flat carborundum stone to almost hone it sharp .
They'd get a copper penny , halfpenny or farthing out their pocket and press the edge of the coin onto the edge of scythe blade that you'd just sharpened . If the coin stuck on the blade edge it was sharp enough for a good 20 min of grass cutting .
Yes you can cut grass when it's wet with a scythe but it does cut better when it's almost dry . Working in long rows cutting out from the standing grass into an open space works best . Being right handed helps for you drop the grass slightly to the left of centre line as you cut .
They do make left handed scythes but at a price .
I don't know if you can still get TYZAC scythe blade replacements , if you can you'll have a scythe for life & it's worth getting a spare blade or two so you'll always have one when it's needed .
