Very convenient in my opinion. It sure is handy
The back piece of the frog is not leather but a hard plastic. While it does hold a scabbard, it only holds it from falling down. Trying to pull out your sword will usually bring the scabbard with it (I have the Classic Medieval Sword). I feel the loops that go around the belt are to long, but I have not used a very wide belt which is what this is probably for.
These are not made to last. They are flimsy and will not last you a day at a fair of any kind. It must be made in China or some other backwater country.
This frog is a must have for anyone who owns a sword of any kind. I have one for each sword that I own!
