Back in the mid 90's I needed a saw for something so I ran out and bought the cheapest plastic handled stanley backsaw I could find. I have been wanting to make a backsaw for some time and decided to just re-purpose the stanley plate and back.
I decided to start with a Kenyon backsaw template with just a few changes. I re-cut the teeth 10tpi rip. I didn't have any saw nuts on hand so made some from 1/4-28 stainless steel nuts and bolts.
I had a small piece of claro walnut on hand for the handle.
I remember the first time I looked at a london pattern handle I though it was an ugly chunky looking thing, but over time I think I have learned to love them.
