I'll share my story with you
A few years ago I was a normal guy working two jobs, not married with no real direction in life but I was willing to spend money on my hobbies, probably because it was all I had going for me.
After a near death experience with a being shot I got my act together and went back to school.
At that point I sold everything I had to pay for school; my truck, my knives, my fishing gear etc
I had close to $3k in knives
Anyway, I stayed knife less but it was for a purpose.
Now I have graduated, I have a wife and two kids and haven't been able to recover the collection lol
I have exactly 4 knives, three of which were gifts but I just can't see myself making big purchases anymore.
Last big expense on a knife was a 940-1 which I saved up for through the course of time
I ended up giving that knife away lol *before even using it* (it was so worth it!!!)
Point is I feel similar to you
I can't spend it because I always end up buying something for either of my two girls or wife instead
However, I do want to get a few Spyderco PM2; a 940-1, and a Bradley alias since the sebenza is pretty high up there lol
I have law school coming up so I better do it asap!
