This dagger is very strong, you can swing it very hard and it won't break. If you hit something with it, it might break. It is about a foot long. Overall it is a pretty good Knex dagger.

This is how the blade attaches. I removed the spacers to make it easier to see. I also removed the other brown connector to make it easier to see. You are done!
