An excelent shovel I found is the Special Forces Shovel by Cold Steel.They wiegh around 27 ounces and are fifty centemeters long.They do not fold but are very robust.I have used it as a light ax/machete and as a hammer for tent stakes.It is bigger than a trowel and smaller than a shovel.A good compromise IMHO.By the way they retail for around $20.00 and I have found them in boy scout stores.Cold Steel's web site iswww.ltspecpro.com.Sorry I do not know how to do dirrect link.
