On a side note, at our school, we practice release techniques while we are holding the knife and Uke attacks us. The results would be devastating if the knife was real. You can do techniques while holding a knife also. It's an interesting thing to explore.
Thanks for sharing the experience.
Absolutely you can use Aikido in conjunction with a knife. One opinion is that the techniques we use in Aikido were developed to allow the bushi to deal with an attacker for just long enough to reach a back up weapon and dispatch said attacker.
Okamoto Sensei did some interesting stuff in this direction on one of her last seminars over here. Worth seeing if you ever get the chance.
