that fishook gun looks just like something i have for pulling down limbs in tree work.. it doubled as one heck ofa tool for defence if you were too outsized..mine had hand grips .. slam it into a big ole suckers arm an start snatching..pretty soon he would probably be outa the fight wanting to get loose.. snatch somemore..
really i never had occasion to use it..it was just there if i was just plain overmatched..that seldom happen ..
i had enough sense to steer it another direction in that situation,,an i didn t look easy ,so they went along with it..
the days of pride ..learned a lot sense then. slim
