CHARACTERISTIC

• very lightweight, efficient V-shape (that's why we call them V-Best!)
• excellent holding power
• super strong and tough - even the thinnest and lightest ones are really hard to bend accidentally when hitting hidden rocks
• available in three sizes - bring a selection for optimal performance in different soils
• the strike head is extremely resistant to being bent over or broken by pounding
• hole for attaching cord
• the biggest stake makes a great mini-crowbar for prying rocks out of poop-holes
