The Burgon and Ball Mushroom Collecting Knife has a very sharp angled folding blade on one end and a brush on the other end...cut the mushroom, flip over the knife and use the brush to gently clean the mushrooms. The blade is top quality stainless steel from Sheffield, England. It has a hardwood handle and measures 7" overall. From the manufacturer, "Mushroom picking can be delicious and great fun, however, if you have any doubts whatsoever about your identification of a wild plant or mushroom, don't eat it!" This should be followed by, "no duh!" Nevertheless, it's a slick, handly tool for "edible" wild mushroom collecting.
