452VL was the first saw I ran at the young age of 11. I now have 3 of them lol. I have the newer version of the 601 which is a 602vl. Heavy saws but they are dead nuts reliable. I have a soft spot for these Japanese saws, they are so well built and I just love how they look. Edit: the 452 is from the late 70s to mid 80s. the 601 is from the early to mid 70s
