This can't be said enough. Buy as many bk29s as possible while you still can!
If you sell the snake charmer and bk5 you really are only paying 100 for the bk29 thats an AMAZING deal.
Just check out the used market on a bk20 you would probably be lucky to get one for 200 for just the single blade not the package deal.
Even in the future if you get short on cash you can sell a set and more than make your money back. It's a no-brainer.
Now I'm not saying buy them to flip them later down the road and I'm not going to think ill of anyone selling one 6 months from now at high price. I very well know the money comes and goes sometimes and blades have to be sold. All I'm saying is buy a user, buy one to mod, and buy as many backups as you can afford.
Lets look at numbers on the bk1 brute and bk6 patrol machete. They easily grab around $200 each if you can find one. There are probably 1000s of each of those made. The bk20 around 450. bk29 around 350.
I don't care how long these take to sell out. The second they are all gone tons of people are going to come out of nowhere and be pissed they missed the deal and they will be pissed at the after market prices. Thats what happened with the bk20s
OK rant over.
