Otherwise known as an English Weeding Finger (the English have a tool for everything) this modern tool is specifically designed for getting "stuff" out of cracks between patio pavers, around rocks and deck boards and any narrow spaces. I also see it as a root hook to dislodge tangled roots…but that’s just me. It is solid stainless steel and extremely well made. Burgon and Ball has been making agricultural tools in Sheffield England for 275 years. I think they have it down.
