JIM-GEM Dibble Bars feature cast blades of special alloy steel. Blade and footstep are cast as one piece so footstep won't break or bend, even under the heaviest tree planting use. Blade "spike" fits into handle to form reinforced joint. Strong welds at the handle and blade joint make these dibbles perfect for bare root tree planting. Works best in non-rocky soil that is easy to penetrate. Blade is wedge-shaped in cross section. Bar is 38" long. Blade is 3"W x 10-1/4"L, 3/4" wide at top, tapering to a thin wedge. Made in the USA.
