2 straps

I just bought a new GS SBGA471. This came with two straps, a leather and metal bracelet. I had no idea this was happening. I love the leather strap, but now need a good spring bar removal tool. 

Please recommend a tool that I can use to switch the straps and not loose the spring bar!!!

Bergeon makes a good tool. $20 bucks or so on Amazon. 

I think the losing the spring bar thing is more on the experience of the user though.
