Anthony, the more I looked at your post, the more I though about something. You say your kids are getting bigger. That means a lot of things. Being the father of three, and grandfather of three, I can tell you that time passes too damm fast. The time you spend with your children now, is going to be priceless memories later on. The heck with knives, sell off what you need to, and go buy a canoe, or take them camping. Spend time with them now, gettingthem on a right track, because that's the best investment you can make. Many years from now, will you enjoy looking back on the knife collection, or the time your kid reeled in his first fish from the family canoe out on the lake?
The time I spent with my dad is my own best memories, with the exceptions of the times spent with my own kids. I used to collect customs. I had many of the big names, but I ended up selling all of them off, and I've never looked back. They were just things. Inanimate things. The people in your life are waaaay more important than things.
I got put out of the army after only 10 years of my intended 20 year career. I appealed the medical discharge, but the army board said the ijuries I received made me unable to be viable, so medical discharge it was. Being married with one kid, and another on the way, I had to start all over again. It was hard. Through the 70's and 80's my only pocket knife was a Buck 301 stockman. Yet, that pocket knife did well in all I needed, and it is in the hand of my oldest son in a photo taken on the Potomac river when John reeled in his first fish. To me now, that photo and memory is worth way more than any knife. John is a grown man now, but every time he see's that photo on the shelf, he smiles. The knife makes no difference, but the memory of it being the perfect day out in the canoe, and catching his very first fish with his dad makes him smile.
Knives come and go, but your children are only your little ones for a little bit of time. How much knife do you need, really? Go walk away from knife collecting, and go spend the time and money on your family. Many years from now, you will be glad you did.
Carl.
