Just wondering what other folks are using for digging in hard soil. Years ago my brother and I started using old US military bayonets. When the ground starts getting hard, the sharp point of the bayonet will break through. It's a little hard on the hand but, it works. Also when sharpened, the bayonet will slice through grass roots like butter. I feel this thin quick cut also does less damage to the roots. We use old filet knife sheaths to carry them. But, old WWll bayonets are hard to find and expensive.My brother bought 8 of them about 20 years ago from Kellyco so we were able to use 2 of them for metal detecting. You can really put a lot of sideways pressure on these things. We have tried, "foreign" made bayonets and they don't give you the feeling that you can put a ton of sidways pressure on them. If you ever get a chance to use a bayonet get a sheath! Don't carry it with the handle in your back pocket. You are bound to cut yourself when reaching for it. Don't ask how I know that!
