My stalwart carry is/was a Vic Compact. 
The mini is really tempting me away, especially as I tailor the tools I feel best suit my standard usage requirements. Here's some of my thoughts on using it the last couple months. 

I've ditched the pocket clip, I carry it in the fifth pocket (sideways) and don't like to advertise I'm carrying a knife/tool. 

Fitted the smaller blade without one hand opening ability. Where I live any knife on your person can be problematic in the eyes of the law. It's still locking but somewhat more likely to lean towards the discretion of a copper. 

I put a hair popping edge on it. Came pretty dull with very conservative edge geometry. Also I want it in D2 or anything better than the soft din or whatever this is. It's very soft stuff. The D2 on my flex companion retains an edge way better. People will pay for better steel blades. Especially in modular tools!! 

Chisel/wire stripper. Super useful. Can open boxes/cut without causing alarm amongst the more sensitive souls. Effective at wire stripping. 

Scissors, it cuts better than it looks suggest and can do nails too. The Vic edges it out here but still a decent scissors. 

Two grit tapered diamond file. It's great and so far has not shed it's abrasive coating in use. One issue I would love to see Roxon improve it is by putting an standard edge file on both sides of it. 100% lacking this and seems like a no brainer to include it. Being able to cut small/thin metal is something I look to do sometimes, so much so I sacrificed two slots to this on my flex companion (t shank). 
They could have also done something to the end of it, namely a chisel edge or tapered to a flat head driver. I want innovation like this where possible on all tools. 

The driver absolutely should be double ended. I want Phillips one end and flat on the other. Vic cyber fit? On this topic... 

******I would pay good money for a slimline attachment that somehow uses the pocket clip mounting point to carry an additional four double ended bits!!!****** This would really be worth the additional width as you would then have 10 bits to use!! I know you smart 3d printer people could make this. If you build people will buy it. 

I fitted a vic pin down the side of the slot the pocket clip lived in. I had to use my file to remove some of the roundness off the head (on one side) so it press fits in. Delighted with this free easy mod. It's surprising how often I use one. 

I've also added a small neodymium magnet to the driver. 

What tools have you added to yours, what tools would you like to see roxon make/adapt/improve?
