The guards are simple and what you would expect from the picture. Bolt heads go on the inside of the cutter, which is fine but seems counter intuitive. These were very hard to get as the retail outlet does not carry. Payment was made at time of order, but there were no updates about delivery date until it was shipped a month later. Received at five weeks. I had to use the cutter twice since ordering, which convinced me that these are not really necessary for my use.
