Plastic Razors Are Expensive

I used to use a Gillette Mach 3, but got tired of spending almost $20 for a refill pack of only 4 blades! I bought an old WWII GI issue shaving kit off eBay. It even came with a pack of PAL Hollow Ground "watch spring steel" blades, but after almost 70 years, they were rather dull. I found a package of Wilkerson Sword blades at the local Wally World for all of $1.97. I bought two packs. Just used the last one up not that long ago. Of course, now that I need more, my WM doesn't carry the Wilkerson Sword blades anymore. Surprise surprise!
Look up theartofshaving.com they may not have WS blades but they’ll get you in business.
