Since about April of this year, nothing has really changed in this setup (except the folder is sometimes different). Maybe someday I’ll switch flashlights.
If that’s a 4Sevens, I don’t think you need to switch. It’s a great light.
My Ontario Rat 1 fits the knife slot, though it sticks out past the end of the wallet by quite a bit. I would think the Large Sebenza would fit, but it would also overhang the wallet. By how much, I don't know. I'm not using it currently becauseI got tired of flashing my knife at everyone whenever I needed my wallet (a particular concern when I was in the UK recently). I had other minor issues with the wallet. Those were not design issues, but issues related to how I use my wallet.
If you PM me your address, I'll send the wallet for you to test fit and try it out for a few days or a couple weeks. That way, you'll know if it works for you before you spend money.
