Blokum was started due to a problem we discovered with different line blocks. They would break or if you were trying to pull a line really tight the line block would give a little bit. So we set out to create "The Better Line Block." Something that would cling tightly to your corner, could hold a very tight line, and something that you wouldn't have to worry about breaking within the first month. Hopefully these line blocks do just of good of job for you, as they have for us!
