That's definitely true. I'm a nut for keeping my knives sharp, from the kitchen to my pocket. A knife is a tool, and only a sharp knife is a good tool.
My pocket knife is a Schrade Old Timer three bladed stockman's knife. A fine tool...sadly, no longer made. I have three brand new ones in their boxes in my top drawer, waiting for the day when I need them. Those should last the rest of my life, since I'm already 61, and still have the knife I bought 10 years ago.
My dad was a nut for collecting knives, swords, and ulus...when he died, and I had to go through all of his stuff, I could not believe how many different knives he had...hundreds of them, most of them still pristine in their boxes...he had those knives that he used on an everyday basis, but just had a thing about having lots and lots of other knives...
So we gave one to each of his favorite nephews, and my son and my husband split the rest of them...my son took all of the swords, as he loves swords himself...
My dad also had a fine collection of billy clubs, and handcuffs...he just liked collecting these things...
