First off as I set up north out of the Hurricanes path, I want to say that my prayers are with all those that have lost so much in the last few days. May God bless them and help them overcome this hardship.
I got my Core today from Knifeworks.com out of the state of LA, I hope all of them are OK. This was my first time buying from them and from start to finish they were great. If they are still in business, and I hope they are, they are great to deal with.
If you like the size and strength of the Supertool 200, you will fall in love with the Core. I compared both of them together and by far I prefer the Core! The Core is heavier than the Supertool 200 but all the blades are longer than the blades on the ST. The awl on the Core is awesome! very sharp point, the saw blade has about a half inch more teeth on it than the ST does. Another thing you will notice is the massive plier head on the Core! but it comes to a very small point, this is the best pliers I have ever seen on a Multi tool.
If I were putting the ST 200 and Core on a scale of 1-10, the ST 200 would be a 4 and the Core would be a 9. You can really feel that 10.8 ounces of the Core. I don't know if a human could handle the 12.2 ounces of the Surge! but I still plan on getting one. And I hope it is from Knifeworks.com.
