I hunt alot of fields and in the timber for Civil War relics as well as old house places that are original settlements in my area. Our ground varies from sandy loam to clay and bottomland gumbo. There are times I will venture up into the hills to look for a few CW campgrounds. The soil there is filled with rocks.
We will often venture 2 to 3 miles from where our vehicle is parked.
For a small digger I use an Ames 7 in 1 Planter's Buddy or Garden Tool. It can be picked up at Lowe's for $14.00. Very well made tool and will not rust.
Another digging tool I use for heavy digging is one that I bought from Wal-mart and modified to fit my needs. I bought a Drain Spade for $20.00. It is approx. 3 1/2 feet long. The blade is approx. 6 inches wide and 14 inches long. The blade had a round tip and I wanted a beveled point. I marked out the angles I wanted and then took it to the grinder. I grinded off the tip into a beveled point and then added a serrated(jagged) edge onto the blade. I then sharpened the edges with the grinder and then used a file to sharpen it more finely. I now have a great tool that can be used for digging and chopping through the brush for a great price. I have used it quite a bit and haven't seen the need to spend any more on a digging tool.
See picture attached for what the shovel looked like before and after. The shovel to the right shows where I marked mine at before grinding.
For less than $40.00 I have two great digging tools that have not given me any trouble at all even in the rocky soil of the hilly areas.
I also use a pair of limb pruners in my bag for cutting roots. I got these locally at a tool dealer for about $5.00.
I use a nylon web belt with two AWP finisher pouches. I had the web belt already and the pouches I bought for $8.00 each at Lowes. As you can tell by the pic the pouches have lots of pockets for putting tools and your finds in.
A Camleback sure is a great item to have as well since we go so far. I also use a pair of leather gloves to keep from tearing up my hands on something in the soil.
I am in the process of making a sling for the large digger that I use. Right now I just carry it by hand.
Yes, you have to worry about sharp tools damaging your find. I hit my first Enfield round with the blade of my digger and put a gash in it. It was in a plowed field so this wasn't the first gash it had ever recieved.
Have fun! I love looking for history.
