I think many peoples "Knife rooms" would be a guarded vision they wouldn't want on the net, and most times a "Knife room" is often something completely different.
I have been in some "rooms" that have taken my breath away but always shy from speaking about who's and where, and to be honest I was intimidated because of the respect I have for the Owners and the privilege to be in the position to handle some outstanding knives and the work involved in getting the collections to where they are now is at times decades of work - hard work and LOTS of money.
I'm always self conscious about contamination on my hands - and ask the Owner to wipe them down after I have handled the Knives - in fact I wear gloves for this reason when I handle my Knives as many times I have come to do a maintenance Mineral Oil / R-Wax only to find the beginning of Rust
Here in New Zealand - especially where we were before had huge Humidity - so its a massive thing to handle knives and trust they wont go "South'.
If I am asked I make it very well known that my collection is in a safe room at a friends, and where they are not many people know, for something that is uninsurable and would be the very first thing for a Burglar to steal- they are not going to be an easy find!
Scary stuff when you think about it eh!
