Greg, your question is rude and impertinent, etc. - to an old curmudgeon who went to grade school in the 1930s. The area was southwestern US. We had a lot of freedom. We wore bluejeans to school. When I was transferred to Canada, I had kids of grade school age; it was against school rules for them to wear bluejeans. I thought that was silly! I believe sheath knives went out in the 60s or 70s here. There are problems in the schools here in areas where the immigrant population is high. Several stabbings. I believe we have a "5-inch" law here for "carrying" and I believe all are barred in the schools- but I think that they allow latitude since I haven't heard of a case like it here.
