I am a land surveyor here in PA. One of the tasks we have when traversing , setting out points, corners and what not is cutting out a line of sight for our equipment through the woods and or brush, "cutting line". Most of the other surveyors I work with hate it, it isnt that easy to do at times. Hundreds of feet of green briar, spiders, ticks, stinging nettle and the like can turn it into quite a chore. Add in summer humidity and tempatures and it can break you down quickly. I on the other hand enjoy it very much. The reason? Where else can you spend hours swinging a steel blade through whatever is in your path. Not just a log or a odd dead tree in the forest but anything and everything in that line of sight. Two handed swings , upper cuts and one handed well aimed slashes with an oocasional grunt or scream with no one around for miles to hear. All the time trudging forward towards the goal. Ive never adventured in a rain forest but i imagine it is much the same. I sometimes imagine myself in midevil times and my machette is my sword. Every so often a mad swing takes a bounce and catches you in the shin or arm. Ive taken two friends to the emergency room for stiches. They think Im a mad man sometimes and It may be true. If I did it to a neighbors land or somewhere i wasnt suppose to be id be arressted or shot but for me its my job. Glorious release. Not just being ready to defend yourself with a knife or other means but real action with a ancient weapon and tool , bringing them down full bore on your target. Then there is the brush ax....4 feet long wooden handle with a foot long steel blade at the top. Barbarian lawn care. Not recomended for the meek. For me it is a true bonus to the job and i hope to beable to cut line for many many years. Today I cut a 90 foot swath through some thick brush and forest and at the end I made one last slash at the briar and ivy wall and leaped out the hole i had made. On the other side was a 8 foot or so hill that i rolled down. I rolled to my feet and came face to face with the two other surveyors i was with. Sweaty, covered in dirt and debris and mostly camo I smiled at them and they laughed there asses off. I moved on to the next line to cut. All in all its fairly safe, safe as you make it, Not many wild animals here in PA, and snakes fear me, there isnt anyone really chasing me like our brave soilders in Iraqi and mostly you can only get a small scar which can be handy with the ladies at the bar.
