I have had this ruler for years. Just now figured it out.
 

I remember buying it at a quilt show when there was a demo and a great discount on the price. Got home and couldn't figure it out. Watched the video but it never clicked. I found it again in my sewing room and since I was cutting four patches I decided to give it a good thinking. It works great and my four patches are perfect each the same size. No trimming needed. Anyone have this ruler?

I'm a ruler-template junkie. If it helps me to make perfect or darn near perfect blocks I'll buy it. But I've never seen this one and now I have to go "google" it to see if I need & want it. There goes my budget for the rest of the month!!

Don't have this one but I do have ones for Flying Geese and 1/2 Square Triangles.

WOW I can't believe the price of this ruler now. I paid less the half that cost from a quilt show vendor. I know it was under $20 because all I had left was a $20 bill and paid for it with that. My last purchase of the day. LOL

It was about seven years ago.

Onebyone.....what website did you use to find this ruler now? I looked yesterday and didn't see it listed anywhere.

Lindaschipper, it's on the bloc-loc website, listed for $50.05. That's a crazy amount for a piece of plastic!

Several years ago, my DH bought me a set of the Bloc-Loc HST rulers. I was stunned--firstly that he actually listened and remembered a stray comment of mine, and secondly that he was willing to pay so much for 3 hunks of plastic. I love the rulers and use them all the time!

I've never seen this one though. Don't think I'll be putting out the bucks for it either.

I doubt I would buy it for that price but I'm glad I have it. It's not a trim it up ruler. I guess it's not promoted as much as the other block lock trim tools.

Finally found it on the website...didn't know the name of it when I posted before. Well, gee, I make a lot for 4 patch blocks for quilts and it would be nice to have this for accuracy. I'm debating with myself. Part of me says go for it and the other says "oh but the price!"

Four patches are usually 2 1/2 squares. This ruler makes cutting the strip set a breeze with the markings and the channel for the seam to ride in. Of course many other sizes can be cut. After using it I will buy one again if this one got lost or broken but would certainly try to find a sale someplace. I will keep a lookout for any good price I see on this and post.

At this point with the back trouble I'm having, anything that eliminates trimming is worth considering.

It's a Block Lock so I knew it would be good, just had to rethink strip set cutting. I wonder why it isn't promoted more. I have never seen it in quilt shops.

I spend a king's ransom on my stripology ruler and I have never regretted it. Sometimes the expensive plastic is worth the cost! I'm a ruler collector to a large degree, especially if I find them on sale!

I have one of those... I might have used it, once upon a time. Forgot all about it until I saw your picture!

There are others I purchased bc of a demo going on at a show or in a shop. If you don't use them right away, you forget what wonderful thing they were supposed to do!

Oh gee...this has been on my mind since first reading the post. Finally gave into temptation and ordered it from Wal-mart of all places, it's not carried in the store. It will arrive in two days and the shipping was free, although they did charge taxes. I have a complete tote or two of strips and partials I could cut up to make a wonderful quilt or more for charity. Even if I did a little each day it would help reduce these totes so they cn be filled with something else.. Love accurate piecing and cutting.

Here is a video how to use it: https://www.youtube.com/watch?v=Esr_-N4NEk0
It's an old video. Strange the ruler hasn't been seen or heard of since. I thought about demo of of at guild as an obscure ruler. I just got an idea. I could do a program on obscure forgotten quilting tools. Remember the 36" long ruler with lip? The original Fiskars ruler and cutter in one? Original OTT lamp? 18 x 24 Elna rotating mat stand? StarMaker rulers? I'm sure other guild members will have some different ones too. Anyone think of more?

I have this ruler and comes in handy once in a while.
When watching the Bloc Loc videos you have to remember
that she is left-handed. So for those who are right-handed
you have to do the reverse. That's what gets confusing
with those videos sometimes. But it's a great ruler for
strip sets.

While I love all the new things that make quilting easier and more accurate, I use the same ruler for almost everything. I don't make quilts for show and admire those who do and share their quilts with us. I really enjoy the time I spend along the way of making a quilt. I love seeing gorgeous quilts at shows. But, I don't want to go faster or be perfect. I think about the quilt my Great Aunt Ann who made quilts without the new things or machines we have, and how much she enjoyed the quilting process. The fabric of that quilt gave out long before her stitching ever did. I think nowadays, women simply don't have time or desire to make quilts like Aunt Ann did, and I sure am grateful for my sewing machines and gadgets that allow us to make such fantastic quilts...and am grateful Aunt Ann was in my life.

My favorite part of making a quilt is choosing fabric prints and colors for a design and seeing the result in a finished quilt. I use what makes the other steps faster and accurate. Greats only had a few resources to use to make quilts thus they used what they had. If they had the tools and supplies we have now they would want every one. There are many who love the hand work and old ways of making a quilt but I don't believe in a second any new tool would have been dismissed by our greats if they had the chance to have it.
