Well the shrinks could call us that, but smart shrinks understand primitive male behaviour
Why do men cheat on their wife? Because they are always looking for a better candidate to carry there offspring. Why do women love large succesfull men? Because they give the best possible security to her children.
The funny thing is that most wives/GF don't mind their husbands/boyfriend collecting these tools persé, but it is the amount of money that flows into the collecting itself.
Women have a hard time to understand why we have the need for a new knife ( we are subcontious drawn too it) while we wonder why our spouses pay a lot off money for clothing, jewellery and make-up.
I believe that a lot of people who work in the field of human behaviour don't object to the fact that you collect these types of tools as long as they stay social acceptable.
i.e. they don't mind you having 10 knives, but buying 10 knives per month and spending all your money is deviant behaviour.
Just like the fact that some women invest a lot of money in remodelling their body is seen upon as deviant behaviour.
Now please realise that everyone has deviant behaviour in one way or another, and as long as the behaviour doesn't become a problem ( financial or social) no mental health professional is going to oppose it.
Is having 200 knives in a collection unhealthy? No, as long as these knives don't interfere with normal human interaction.
Once the knifecollectors starts losing his friends/ partner, losing his job or gets into financial trouble or with the legal system it is seen upon as a problem.
So this is the question we should ask ourself, is my knife hobby grown in such a way that it hinders me in interacting in a normal way with other people?
When the answer is no, there is no problem
