I almost always hike alone. Ive had a couple of overnight trips with my best friend when i was 15-16 years old, and last year i went on a canoe trip with my stepson, and thats about it.
I'd really like a dog though to keep me company! But my lifestyle right now, dosent allow me to have one.
Ive always been a loner, and my hiking gear and plans reflect that. Every single piece of gear i buy is made for solo hiking and weight/durability/field mainetenance etc. is taken into consideration before i shell out.
I always study the area and terrain where i'll be hiking, so i know what to expect and in case plans change, i know which way to head out for the nearest town. In the last couple of years ive started giving my girlfriend info about my trip, just in case. But i guess its more for her sake than mine. Gives her some piece of mind, i guess.
My knives, are just regular knives. I dont buy knives based on the fact that im a lone hiker. Ive got Fallkniven, Becker's, Ontario, Chris Reeve and RAT to choose from, and i have faith in every single one of them. I choose my blade based on the terrain ill be hiking, season, and duration of trip.
Even if i were going on a trip with somebody, i dont think my gear choice would change. I'd still take everything that i need to get me through in a safe and comfy way. I wont rely on others gear/knowledge.
