from junior school age onwards two sheath knives (one from each older brothers stash) then my own sheath knife . loads of small pen knives (came as gifts in those bubble machines) two proper pen knives, my own sheath knife, a throwing knife . an infinite supply of modelling knives. An army folding knife probably issued to my dad in he was in the home guard .
A home guard manual detailing tactics and improvised weapons ( I still know the recipe for a “proper Molotov cocktail”)
numerous home made bows and a really weak homemade crossbow and lots of shop bought catapults after realising knicker elastic just did not cut it .
My cousin and I even smuggled an air rifle on holiday to Scotland.
an untold number of “camp fires”
I grew up a pacifist and only ever cut one friend accidently with broken glass and one accidently with a saw.
I think you live near a “boy” and you should either return his bow with a note saying be careful with this or just bin it and stay stumm.
