Went spade shopping today and found this folding army spade. A bargain from Harper's Bizarre in Malvern at £12.50 and I've taken the old loop off my maglite holder and put it on the spade and it hangs perfectly on my belt.
A BIG PLUS is that the blade points down - don't climb any fences or styles with a spade on your belt, especially if the blade is pointing up - I tripped once and the blade very nearly went into my rib cage - only saved by thick winter clothing......
Be warned though, I bought the second hand one NOT the new one. The new one looks the same but the bolts are half the diameter and RIVETTED in. The used ones have a very robust nut and bolt.
