It took me about an hour to figure on how to post, but it is worth the effort. First, welcome Yuri, your very versatile tool is great! I’ve been learning
gardening for sixty-odd years, most of them in a very small town in Maine. My dad had a similar tool, I think he purchased at Sears back when the catalog doubled for
outhouse reading material. It did have a removable blade for sharpening, but I like your simple and sturdy design better. I am now wrangling weeds in the desert Southwest and this tool will do just that and more. Thanks to your efficiency in design this tool is a
gift to us gardeners and weed-fighters. Best Regards
